If you're willing to play disk jockey, I could imagine doing this completely in software with a single DVD drive. After all, this would probably be part of a backup application, anyway. I don't see any reason to dedicate hardware to this. Furthermore, it is certainly possible to have more data than available DVD drives, so having all DVDs online at the same time is impractical in the general case.
Building a simple hack couldn't take more than a day of hacking (at least to write a proof of concept).
There's no reason why you couldn't read each of the DVDs in serially and incrementally rebuilt the lost DVD. On recovery, you should only need enough space to hold a single DVD to rebuild the remaining disk.
A disadvantage is that the data cannot change while you write all N+1 DVDs and restoring would require lots of DVD swaps (regardless of whether you've lost a DVD or not) and the ability to incrementally write files with gaps in them (not an issue with most filesystems).
Pray tell, what are you going to do with just a network? Store bits on the wire and network card rx/tx buffers? There's gotta be something big on the other end of the cable, dude.
Here's one I've been saving, just because it's rather amusing. As a whole, it doesn't make sense, but the mental images are fun.

The hardware sales might be neck and neck with the game cube, but the last I heard, the Xbox unit of Microsoft was still hemorraging money. They thought they'd make the money back in software.
Forgive me for my ignorance, because I have only voted with lever machines, but why does the voter have to handle the card? If there's only one per machine, why should it ever leave the machine?
The engineer in me also asks how many insert/removals can the reader handle? Don't they worry about static electricity? Aren't the maximum number of writes measured in tens of thousands of cycles?
AFS dies horribly if your clients lose sight of the volume location or file servers. As long as the machines are well-connected, it works great.
As far as Kerberos goes, I'd suggest the new ORA nutshell book "Kerberos: The Definitive Guide". While it doesn't go into AFS much, it explains how the thing really works and how to configure MIT and Heimdal Krb5.
I have both the MDR-NC20 and the older Bose model. If you get the Bose, make sure you pay the extra money for the newer model, otherwise you're better off with the NC20's. The older model has an annoying dongle that takes two AAA batteries. It also requires the batteries to be operating to play any sound. It also seems to amplify the bass a bit more than I like, but some people might thing that's a good thing.
The newer bose model has a battery up on one of the ear pieces (I believe a single AAA), no dongle, and passes sound without being turned on, iirc. It also has a single cord going to one earpiece, instead of the Y split. Both bose models have quite a bit more padding than the NC20's and are closed earphones.
My biggest problem with the NC20's was that I kept stressing the weird mini-plug thing on the bottom of the cord and it finally broke. Fortunately, I'm handy with a soldering iron. Other than that, I think they are a great pair of headphones.
I believe Bose has a 30-day "test it out" period with their headphones, so you could give them a try.
There are a whole bunch of interesting optimizations you can can do once the program is already running in the JVM. For instance, the IBM Jikes RVM will periodically queue methods for recompilation/reoptimization (with profiling information) after executing the method a certain number of times.
Agreed. I should have justified that this is in Pennsylvania. The severability clause is implied in contracts here, although it's good practice to state it anyway.
IANAL, but I am a small-time landlord. If something in the contract is illegal, that does not invalidate the rest of the contract (although that one section may be invalid). As far as contract writing goes, it still doesn't hurt to state that in the contract, but it isn't required.

Unless he's using wireless, why can't he? It's not as if there are war drivers trying to out-geek him by sniffing his packets.

You can claim that your DSL modem literally runs faster than your neighbor's. After all, their DSL modem just sits on the shelf and blinks happily.

See if the department can afford an HP Digital Sender. While they're quite pricy, they'll feed, scan, and email you a PDF.

For the love of god, we should all hope that such confusion is limited solely to the poster.

Don't forget that writes are generally slower than reads and hdparm doesn't test that.
In any case, toying with the DMA and PIO modes using hdparm may help a bit.

OJ Simpson dug the dish at nicely discounted price.
I just asked jeeves whether he denounced it and given that the top 5 links are "Sponsored web links", he certainly does support it.
On the other hand, has anyone ever gotten a straight answer out of Jeeves? I didn't think so.

Yeah, it wants to be free.
