Hi guys, At work, we use an HP server/thin client solution running Windows Multipoint Server. It works quite well. The thin clients are small enough to iso mount on the back of an lcd monitor. Each client connects to the server by a single USB connection and has an svga port, ps2 mouse and keyboard ports as well as an audio mini jack for speakers or headphones. In a business or educational environment, the system is wonderful. The biggest drawbacks I can see in using this in a vehicle are: 1) Each client instance requires a separate Windows license in addition to the one for the main server. 2) The server needs to be a bit of a powerhouse. We use a 3ghz quad core with 8gb of ram for our server. 3) Windows Multipoint Server is 64bit and based on Windows Server 2008. I have run into a good deal of software that just will not run on it. With software such as GoodSync, we were told we needed to purchase the very expensive Corporate license simply because it was a "server" OS and the standard business license would not run on it. All in all.... I believe that a main system with several single board computers such as the Raspberry Pi networked to it for each zone would be a much better solution. The RSP is capable of HD video and is capable of doing quite a bit in stand alone use.
