The problem as I see it is that is a cluster you want to squeeze every cycle out of the chips for processing a large problem. You can create a 'cluster' of workstations to process a common problem by having each work on a sepaerate piece of the dataset (Seti at home, renderfarms etc) but that's not we're really about. The aim of beowulf and similar projects is to combine a number of distinct units in such a way so that they attack a problem as a single unit.
Yes you can do it on MS. No you would want to. Why? 1. You can't shave away the parts of the OS that are stealling cycles. Who really cares if the thing can allow you to click on icons or check email while it's processing. 2. You cant rebuild the kernel to include or exclude features. A number of Beowulf type sites rebuild the kernel to include interprocess communication channels to syn the nodes. 3. You're running the system as a single unit through a single user controller, so why the hell would you want to license each node.... 4. Doing it through Linux would piss off MS
What I see as the big concern is the quality of digital images compared to film. Digital equipment is aimed a diferent market that sat the traditional 35mm SLR. It's smaller and lighter and allows you to get your photos to the web without that nasty development business. But smaller means the lens is smaller too. The smaller the lens, the less light can travel to the focusing plane, and the more you notice abnormalities in the end image. Also unless you buy a very expensive digital studio cam, the top res is what 3-4 megapixel? And most papers are all about cost cutting, so they're not getting the expensive ones. The only consider digital to get out of paying development costs. A single 35mm frame on average film stock is at least 9 megapixel, and can still be digitised easily.
As someone said in another thread, some of the greatest images in the history of photo journalism are where something in the background that went unnoticed at the time is seen and enlarged. Digital, at present, doesn't give you enough detail to focus on the background.
There is a Linux for PS2 released by Sony for Japanese and US consoles. I think it was a limited release, but you might be able to get your hands on a copy. I haven't seen it, as the version for my console is still not released, but I believe that it supports X and that someones ported Mesa, so you should be able to get OpenGL going.
This link might help.
There's two main thing to consider here.
First they've already got it, and if the agencies can't break it why would they chnage the algorithm they've already got.
Secondly, one nation, and once again it's the US, can't make a global poilicy no matter how good their intentions. I'm Australian, and glad of it. Our governments a complete bunch of muppets, but they're ours and should be able to decide policy for our country. Of course they can't, but we keep hoping that one day one of our politicians will make a decision other than what to have for lunch (that's when they're not in parliment, in which case they eat what ever is on the menu)
So here it is: How fucking stupid does the US senate have to be to ask ever nation in the world to subscribe to the idea of encryption software that allows other nations agencies to gain entrance, especially if that back door is maintained by one government.
The answer, I hope, is not that stupid.
Besides, a backdoor will only help you if you know what transmissions to intercept, and if you know that then human intelligence would probably be a better alternative.
This is another example of what is beginning to irritate us users who are not residents of the US of A. The senates decision means exactly zilch where I live, but I still get spammed and spammed by US companies sending links to porn sites that are in theory illegal in Australia.
To me, spams are like virii. The are uninvited and consume resources on my system. If a person can be prosecuted for creating computer based item that places itself unwanted on a third parties system, then shouldn't that apply to all such cases.
If I didn't ask for it, and it is now in dirrect and immediate response to my action (like clicking on a web link) then it should be considered an intrusion.

Personally, reason 4 is the main seller for me:>

Gotta love a knee-jerk reaction
