Why don't you get a small VPS system? and upgrade if/when you need more power.
You get redundant Power/Disk/Networking all for a much lower cost than a dedicated box. If a phyiscal system dies (quite unlikely anyway) they can move your VPS to another machine and it should be up again pretty soon - which should be good enough for that many users.
It seems they are pushing this as new. Though Nvidia's own Quadro cards have had this for years even ones which were based on GeForce 4 chips (look at ones with 3pin stereo connector on http://en.wikipedia.org/wiki/Nvidia_Quadro).
Nvidia have always made it so that only expensive Quadro cards can do Quad Buffered stereo which is what is needed to do the rendering properly (a double buffer for each eye). IR-glasses have been around for several years (http://reald-corporate.com/scientific/crystaleyes.asp) and operate by pluging a transmitter into the 3pin port onto a quadro card (or their are other methods such as blue-line stereo). Shutter glasses in the past have been too expensive ($500-1000) though mass-adoption should bring that down.
Stereo also works under OpenGL on Linux so I don't see the problem with that.
The only thing that seems new is that Nvidia are pushing it, it may end up on consumer cards and the stereo conversion of existing games.
Actually I thought this would be a problem, since I hate 60hz and sometimes notice 75hz, but I have found 110hz-120hz CRTs not to bad in stereo and 105hz on DLP projectors is actually quite good.

1. Those 'Ad-Hoc' solutions you dismiss are perfectly capable of managing the machines, I manage over 200 RedHat Desktops with just (RedHat) kickstart, rsync, SSH keys and scripts. And the best thing is, you can do anything, not just what Active Directory lets you do.
2. RedHat, Novell and Ubuntu all provide paid support options - the difference to Microsoft is that you will probably get an almost direct line to someone who can really fix your problem because they contribute to that part of the distribution.
3. It seems that lots of Windows sys admins would like the chance to work with Linux instead, but they just lack the experience to move into a job doing that. I would expect any kind of move to Linux could interest existing Windows sys admin into Linux support with the back up of training and a local Linux sys admin. Also in my experience Linux sys admins are able to apply changes much quicker than Windows folks - so you don't need as many staff, so you can pay them more.
Does anyone else just think this whole situation is crazy? With YouTube and iTunes coming up to make broadcast TV irrelevant the TV companies are still charging or at least restricting the information about what is on TV. Why don't they just have the listings on their websites in XML (XMLTV or TV anytime). They surely the money the make is insignificant compared to the potential of iGoogle plugins, facebook applications and other mashups which make the information more useful.
I'd say since you can store upto 1024 in 10bits, so call that 3 digits, then:
100,000 / 3 = 33,333.33
33,000 * 10 = 333,334 bits (rounded up since you can have half a bit)
333,333 / 8 = 41,667 bytes

Some of the glasses on the market already, fit quite easily over your existing glasses, and that seems to work quite well. http://reald-corporate.com/scientific/crystaleyes.asp
Netscape Communicator 4.5-4.8 had roaming profiles which sync'ed your bookmarks with a LDAP server and your address book, cookies too. This feature kept me using Netscape long after it was really dead, for some reason people seem to have forgotten about this great feature. http://www.acns.colostate.edu/aspx/www.acns/bulls/ nsroaming_whatsroaming.html http://www.itworld.com/AppDev/1411/LWD990901netsca pe/ http://www.geocities.com/petru2/netscape_roaming.h tml

I note that the BBC offer it's data: http://backstage.bbc.co.uk/data/TvChannelFeeds?v=x eg

I love the way the site proclaims to me "you must have flash player 8", well actually, no I don't.
