I've seen the system working with four users, each having their own view, and it works like a charm!
Abstract:
In this paper we describe our implementations of multi-user stereo systems based on shuttered LCD-projectors
and polarization. The combination of these separation techniques allows the presentation of more than one
stereoscopic view on a single projection screen. We built two shutter configurations and designed a combined
LC-shutter/polarization setup. Our first test setup was a combination of mechanical shutters for the projectors
with liquid crystal (LC) shutters for the users' eyes. The second configuration used LC-shutters only. Based on
these configurations we have successfully implemented shuttering of four projectors to support two users with
individual perspectively correct stereoscopic views. To improve brightness conditions and to increase the
number of simultaneous users, we have designed a combined LC-shutter/polarization filter based projection
system, which shows the most promising properties for real world applications.
Maybe you should give VTK, OpenDX, VisIT or Paraview a try, all of which are just some of the scientific visualisation community's tools of choice (and hey, they're OSS, mostly cross-platform as well).
You might want to check out the bags section of Gravis footwear. Padded "floating" laptop holster, big enough even for 17" desktop replacements, and plenty of pockets for all your cables and reasonably rain-proof. Although they might be a little over your initial budget, at least it won't make you look (and feel) like just another nerd who's equipment would likely be stolen. I myself carry the 2003 special edition Metro bag, and everybody is amazed that it contains a laptop...
I'm walking around with ideas similar to these for over two years now. The main aspect is to bridge the gap between public and personal transport (and combine their advantages). Think of it as freightcontainers for human transport as well, or "package based network" human transport (similar to computer networks)
1) I want personalized transport: I love the flexibility and privacy of my own car. At the same time, I don't want to control the vehicle ALL the time. Let the system do the controls for me on the larger tracks/highways if possible, while I do some work or entertainment. I hate public transport for their transfers, lack of privacy,comfort and flexibility.
2) When I travel by car, I travel alone with little or no luggage ( 80% of the time). All I need is a seat, a small storage and protection from the elements. (see it as a TravelPOD or tPOD). It can be lightweigth, transparent and equiped with everything I need on the trip. If I need extra's, just connect/order extra pods.
3) Don't carry around your personal engines all the time. Here I am wasting most of the energy for hauling the 1000 kg of useless steel with me wherever I go by car. Just have the TravelPOD(s) connected to a
means of propulsion which is best suited for the route to be travelled, and be automatically transfered to other types of propulsion if necessary. (see 4)
5) A main transport system will act as a network, transporting tPODs from node to node while controlling congestion, speeds, and transfers at intermediate nodes. Based on my selected destination and preferences, the system will select the appropriate route and the means of transportation. There can be high speed intercontinental vacuum trains, city subways, or trucks and trains which all carry loads of pods. To connect this system to the "normal" world, PODs can be put on regular carts to drive the last few miles yourself.
Example: I want to go from my appartment downtown to my work at a remote location. At home I have my personal TravelPOD connected to a small electric "base-vehicle" to do the travel from home to a nearby "transfer point". I drive it myself, cause there is no (and needn't be) automatic steering everywhere, and select the final destination. Here the tPOD is transferred to a city transport, while the base is put back in public storage (I don't want my own in the city, cause I don't care about the base here). At the city's main node,I'm transferred to a high speed-high capacity connection. The train takes me in my tPOD (together with 1000 other PODs) to a station nearest to my destination, transfers...etc..etc. When I arrive at the station nearest to my destination, I select my companies "off-road base-vehicle" cause I need to go the last few miles on dirt roads.
This type of system could be gradually introduced into the existing transportation means, starting with intercity connections by trains.
Can you Imagine? Get rid of energy waste, get rid of hideous traffic jams, get rid of hours of driving on a boring highway. Spin your own songs, browse the web, do anything on your trip.
Anyone seen similar ideas, please let us know. Now I think of it, i'll write my thoughts and discussions up in my site and start sketching some scene's and scenario's
Wouldn't it be a nice experiment to use multiple next-generation PCI-X "graphic" cards on one system as the ultimate set of matrix co-processors? You could create your mini-cluster inside one box! Anyone seen or tried this yet?

The guys at Dresden 3d have already done this: TFT with integrated stereocams to track the eyes and a automatically adjusted (mechanical) lenses. A friend of mine told me it was amazing. I sure hope its better than the "regular" lenticular display like the Syntagram I've had on my desk for a couple of days (ouch, my eyes!).
