No problem with incompatibilities. There are the two mandatory schemes, which must be available on all devices. If a particular manufacturer wants to implement the optional schemes then that scheme can be used to communicate with similar equipment, with CCK or OFDM as a fallback.
Although the data rates for the optional schemes are no faster, it's possible they may be more robust in some circumstances, which I guess is why they're there.
There's already negotiation in 802.11b to support the various codings already used (1-2Mbps, 5Mbps, 11Mbps). Since 802.11g is meant to backwards compatible this must still be used.
They're both good, journalling has benefits in some situations, softdep has benefits in others. (Softdep will also allow for some nice features such as snapshotting, like the NetApp filers do - an easy way to rollback the entire system to an earlier date, or to perform consistent backups with minimum downtime).
Of course, you can deal with source with it's smaller updates, and still easily package your own binaries to install to lesser machines, giving you the control of what goes in, keeping the bandwidth use low, and not taking forever on 486 firewalls.
Linux doesn't really have an equivalent to softupdates. Async is not very safe in UFS, it's not a good idea to mount FreeBSD partitions async unless you don't really care what happens if the systems stops without unmounting.
Netbooks are still listed here. This link suggests that IBM may produce a Linux port. Since they use flash instead of hard-drive, the distribution would have to be limited. Though, perhaps emacs can be ported to run natively under EPOC32 (or perhaps it already has..)
Whatever, losing the HD is one excellent way to cut battery consumption to the minimum (on whatever type of machine you use). Boot from flash and use a ramdrive for temp storage if you need it... I wonder if any laptop BIOS supports booting from flash on PCMCIA or if you'd need flash which can attach to IDE (used in conjunction with a 3.5"-2.5" IDE converter and placed in the drive bay....assuming it fits:)
Ahh! That's how they can do it... The news sites should monitor for sudden drops in the stock markets, and when they occur switch automatically to text-only:-)
There's some near-line-of-sight kit available, most is for large ISP systems (Cisco and others), I think Wi-Lan have something a bit smaller that's near-LoS (though it's still quite a lot more than 802.11b pricing..) If you need to be totally non-line-of-sight you'll have to drop the speed *right* down (and probably need an amateur radio license too).
They're probably much more concerned about file-sharing than copying. Copies are automatically limited to some extent by media costs.
If only the dumb media companies would realise that mp3 is good advertising, and just slightly increase the value of the CD as a whole -- spend time on producing interesting packaging (take a look at The G-Stone Book compilation for example, and while you're at it if you like Kruder+Dorfmeister etc buy a copy too because it's damn good;), or include a mail-back card for a free poster or something, plenty of people would be quite willing to pay rather than copy...
Not if you use a reasonably decent CD player and an external ADC (either a *good* USB soundcard or a standalone ADC into a soundcard with digital inputs). Analogue sound can be pretty d*mn good, but the inside of a computer is a *really* bad place for analogue signals to survive intact.
So, if a large-scale pirate duplicates the CDs using a stamping machine, and distributes the copies in cases which do include the logo, they're breaking trademark law too! Nasty...;)
A WAP11 will do fine (runs as a bridge). Setting up WEP will raise the bar significantly on someone getting free access, anything needing stronger crypto can probably go through your VPN.
There are internet-drafts about VPNing through NAT gateways, but it doesn't seem to be mentioned on the websites of the big VPN manufacturers, so it's probably not in shipping code yet. But it is supported by Checkpoint and Nortel so should be there sometime... (google 'VPN NAT' should get you started for info on that one).
And both of those are totally different to the WAP11, which has wireless and one wired output. (The WAP11 supports wireless network bridging to similar units, both point-point and point-multipoint).
Hundreds of meters? Unless the repeater's going on top of a hill (or some other obstacle too tall for you to just raise your antennas higher), you shouldn't need it. (I take it you are using reasonably decent external antennas..?)
If you need a solar-power 802.11b repeater, buy a box, add PV cells, batteries and whatever APs/bridges you need. (If you have wireless clients at each end rather than APs, you should be able to put the AP in the middle).

You don't need tunefs(8) now, they can be done in sysinstall. This makes it much easier to enable softdep for root :)

And here's one that's a bit more pleasant.

That's not what UK news reporters have been saying!

Ahh, finally. That pricing must be so that 'merkins realise how much people in Europe have to pay for their music...
Your own composed/performed music won't have the 'no digital copy' flag set on the data stream, so SCMS won't kick in.
So, return the electronics rather than the CDs... :)
Ananova usually works too.
That's what Opera's "user mode" is for. (3rd icon along next to the address bar).
Not universal. In UK it's usually on purchases >£100 (I think a few card issuers extend this but nowhere near all).

Captive portals like NoCatAuth are necessary, since 802.1x isn't widely supported yet.
