it sounds to me like your first concern should be that 24 households are on the same hub.... i for one wouldn't feel comfortable knowing that anyone else in the area could just open up ethereal and check me out. look into buying a 24 port switch for privacy's sake; i'm sure your neighbors will be more than willing to chip in for one if you explain how they differ from hubs.
as for the bandwidth issue, 24 households sharing a single DSL line is a bit of a stretch, especially if some houses have several computers in them. it seems strange to me that people don't want to pay for their very own DSL line but at the same time expect good bandwidth!
bottom line? you will probably not be able to do this cheaper (in the long run) than everyone getting their own DSL connection. of course, since you already have the closet with the hub and the cables run, you could set it up so that small groups of neighbors can agree to split a single DSL connection -- presumably those with low-bandwith habits. just buy a small hub/switch for each group (or a managed switch that does VLANs). that way, the bandwidth hogs can pay for their own line and the rest of the users can get a lower per-month cost by collaborating.
check out the AVC Soul Player! the one i own just died after 4 years of abuse -- i always had it plugged into my car stereo (i bought it for $120 when low-end in-dash mp3 players were $450) and i guess it just couldnt take another winter with -30F nights.
anyway- if you can get one of these, definitely do it!
they play CD-Rs and CD-RWs no problem.
they support mp3 and wma (up to pretty high bitrates and VBR)
120 second skip buffer, which saves a lot of batteries
you can skip ahead by song, by 10 songs, or BY DIRECTORY
THIS THING UNDERSTANDS DIRECTORY STRUCTURE! you can naviate alphabetically sorted folders AND SUBFOLDERS and see their names while a song is playing. this is infinitely awesome!
you can change the fastforward/rewind speed, up to 6x
automatically resumes where it left off on the cd, not just on the current cd but on any of the last 10 cds it played. you can turn that option off if you want.
supports ID3 tags, but there is the option to turn them off too
has a wired remote and a line out, which makes it great for your car (i clip the remote to an easy-to-reach part of the dashboard)
this player is great for long road trips, because not only does it save a lot of shuffling cds in and out of the player, your friends can browse what else is on the cd while a song is playing. its also better than USB/flash media players when you're on the road, because its so much easier and cheaper to bring a stack of mp3 cds instead of a laptop and/or memory sticks.
its the little things about this player that make it great... and there are SO DAMN MANY of them.
i feel your pain about how clicking the wheel is rather stupid compared with clicking an actual button. the mouse i'm using right now, logitech's "mouseman wheel" ps/2, has the 3rd button under the thumb instead of between the right and left. it doesnt take much getting useful, and i find its more natural than normal 3 button mice... for 3 buttons, i have 3 fingers instead of 2.
this mouse is logitech model # M-CW47 if it matters.
joking aside, what's really important is that you show prospective employers that you are not your tatoo; that your tatoo is you. in other words, if you act like you are is supposed to say something for/about you and they are supposed to figure out what it is, chances are they will assume that you got it to be "different" (antisocial) and that you are probably not a good person to have on the team. instead, if you understand that people will have that reaction and be up front about what your tatoo means, and explain it to them ("this is in memory of my [family member, friend]", or some other idea equal in its permanence to a tatoo), then they will get a better idea of what it is you care about and, by extension, who you are.
i'm using a mini-itx (800 Mhz version) as a home server right now. i have it mounted to a wooden shelf, without a case.
the board and hard drive (2.5" laptop drive) use little enough power that i was able to take the fan out of the power supply without it overheating (its been 10 months). with adequate ventilation you should be able to rip the fan out also- just remove the cover of the power supply or drill some extra holes in it so the air can circulate.
mini-itx makes 2 fanless motherboards as well, but you will sacrifice either cpu speed or extra cash to get one.

Wireless VOIP?

actually... i just had this thought:
do you want the microphones themselves to be wireless, or just the link between the audio signal and the disk? what if you ran your microphones to a server with a few sound cards and wireless ethernet cards?
then you could record the signal data to disk via a wireless NFS mount. plus, you could assign each wireless card to its own AP on a different channel and aggregate as many cards as you need to get the required bandwidth.
does that sound like it will work for you?

i was working as a sysadmin in a small office environment, and we found a new use for an old HP printer that had been sitting in the basement for a little over a year.
a few days after i had put it back in service, it spat out (without warning or provocation) a document dated from its previous life. spooky.
most car equalizers are 5.75", so you have to be a little creative with cutting off that extra half inch to squeeze it into an old cdrom case. but for a cheap/free secondhand EQ (and that 1X cdrom that you were never going to re-use), its definitely worth the effort, visually and audibly.
i feel bad that there are only 20 or so comments so far, and a bunch of them are modded "funny"...
that being said, here's my contribution to the positive experiences:
twice now, i've been able to take a portion of code i've written for one of our products and turn it into a utility that the rest of the group can benefit from. everybody wins; the code was already written, i get to feel important, and everyone else's work gets a little easier. as long as you dont take more than an afternoon to work on something like this, your superiors should be ok with it.
i thought of that-- getting a slim laptop-style drive and dremeling it down to just the laser and motor assmebly. know of anyplace to get cheap ide/usb ones?
that's good to know. did you mount the hard disks in any special way as a precaution? also, what method do you use for getting your music on and off your 13GB drive?
one of the advantages for cds (or any interchangeable media) is being able to bring the music collection on the road from home to work and back, and be able to listen to it in all 3 places. i'd consider carrying the hard disk with me, but i'm very prone to dropping things... especially expensive things...
well, i was really just asking if such products existed... the project itself is another computer-in-car concept, just for fun. the intent is to somehow work the components into the dashboard. here's the reasoning behind it: hard drives are subject to vibration. flash drives have expensive media, and i would need to buy 2 (one for the car, one for me). a regular cd drive would be a little big for the dash. but, the media is cheap and mini cds would be small enough to work into the dashboard.
if you can think of a better combination of durability, compactness, and low price, let me know...
there are many types of DSL... ADSL, SDSL, HDSL, VDSL, SHDSL, etc. they are divided into 2 main groups: Symmetric and Asymmetric.
the "symmetry" of a DSL modem refers to the way the frequency spectrum is divided up. above the voice spectrum, there is an upstream data spectrum followed by a downstream data spectrum. in Asymmetric DSL types, the upstream spectrum is much smaller than the downstream spectrum. in Symmetric, they are the same size.
since ADSL modems have different size spectrums for upstream and downstream, they do not connect to each other.
Symmetric modems, on the other hand, are more readily connectible to each other. but, most need to be configured so that one will act as the "central office" device, and the other will act as the "consumer premise" device.
the other thing that needs to happen in order to connect symmetric devices is configuring the ATM settings properly. DSL devices use Asynchronous Transfer Mode to transfer data across the line (this has nothing to do with your local network). most devices use a PVC of 8/35; it doesnt matter which one you use, as long as they're both the same.
so, your best bet would be to use two Symmetric modems with consoles that you have access to.
I'm not trying to discount the problem that you're having... I just think that regardless of what advice you take from this forum, you should also seek the advice of a lawyer.
This issue is definitely something the GPL crowd would like to be aware of, and its good that you posted it, but I think your best advice would come from a legal professional.
i remember seeing (several years ago ) what would have been the equivalent of a power strip for ram. it was a ram-sized board that fit in a 72-pin simm slot, which itself could hold up to 4 simms. i'm not sure if they still make them, or if they do, i'm not sure if they make them for any of the newer ram types.
you've given very little background on your setup. where most people would try to spread one computer's data over several drives, you are trying to spread one drive over multiple computers. i have no idea why you would want to do that, but this is what i can offer:
why don't you just find an extra comptuer and make an NFS server? the reason that you are not finding much information on sharing a SCSI drive is that there are a lot of better ways to do it. what sort of speed are you looking for? a 100Mbps network can deliver data comparable to having the drive attached locally, and you won't need an incredibly fast computer to serve it.

there are plenty of reasons for and against case sensitivity in languages... so why not allow both?
just make up a compiler directive or something that indicates whether to de-case-ify your code.
