I built a small Beowulf cluster. It was actually very easy, apart from writing the MPI enabled code.
Step 1: Install the lam packages on all the nodes Step 2: Create an account on all nodes, and use a passphrase-less ssh key to avoid prompting. Step 3: Compile your code with mpicc (rather than gcc) Step 4: Copy to all nodes. Step 5: mpirun C./your-prog
Admittedly it was only a 4 node cluster, but hey;)
Please, someone break it to me gently if this wasn't actually a Beowulf cluster;))

* RS232 serial port
* USB port, configurable as either 'host' or 'client' device
* Bluetooth wireless LAN
* GSM/GPRS cellular communication
* Biometric fingerprint sensor
* Size: 5.4 x 3.1 x 0.8 in.
* Weight: 8.8 oz.
Software:
* Linux operating system (2.4.x kernel)

Yeah, sounds great, but so many companies wouldn't be able to move in time, or their data would be inaccessible, or there wouldn't be enough decent Linux consultants, that many many companies would fold, and many more people would be out of work.
This would then stop people spending which would hit the retail sector, which would all have a knock-on effect.
Companies need to work it out for themselves, have time to plan migration strategies, and do it themselves - a one day on, one day off effect would affect the EU very badly.
Thought - let's supposed that the EU fines MS $10bn. MS retaliates against it by withdrawing from Europe, and stopping people in Europe from buying MS, and downloading patches etc.
Sounds great to us Penguinistas, but the impact on businesses that have (through their own fault) got stuck in the Microsoft way would be immense.
Microsoft have long ago given up trying to make money from home users on their OSes.
They'll still try and frighten corporates into paying for licences, but if "everyone" uses Windows at home, then it'll be more prevalent in the work place (maybe).
They've given up ages ago. I don't even know anyone that buys Windows any more.
PS. I'm running Linux (GNU/Linux, whatever) at the moment.
I only found this out recently, but the freeswan.org site lags behind the actual development of freeswan quite a lot. A nice friendly guy runs freeswan.ca, and keeps it chockablock with all the latest patches and stuff.
I just hope Hans doesn't rush it just to meet this 7 day deadline. Can you say massive data corruption/loss ?
Things should be allowed to mature and be tested. Much like Grolsch. "We only let you drink it when it's ready".(tm)

...although apart from forgetting to compile in support for the Smart Array controller and getting Root FS not found, I've never seen a "real" kernel panic.

I've run RedHat since day 1, and I'm used to the way it works. Conversely, I find that Debian has strange ways of doing things.
All this shit about installing tonnes of crap in the default install is rubbish - nowadays at least.
Why doesn't Debian support Compaq Smart array controllers on it's boot floppies? There's not really any reason. (And don't give me that space issue).
Debian is good for stuff you want to run, and jsut type apt-get update && apt-get upgrade once in a while, but to most people, RedHat is Linux. How many times have you heard someone say "Have you got Linux 7.3?"
Get people using Linux for Gods sake. Then they will learn. Then you can give them unfriendly but powerful tools. But don't dump them off at the deep end first.
No better way than to get the Slashdot crowd to do a quick bandwidth, hardware and security test!

www.rdesktop.org works wonderfully with WinNT TS, and Win2K TS.
Are there any kind of patches for it that will make it work with XP/.NET (RDP 5.1)?
Check out this phone - it looks pretty good.

Now this is a bad idea.
The GUIs is good - stop newbies getting confused when they start out. But the shells?
Once you know your way around a shell, you know about chsh, or editting the passwd file to change it.
I mean, I only use bash (you use what you know) but I can imagine this upsetting **lots** of people.
Imagine all those shell scripts breaking on an upgrade....
