At the moment, there are several device servers available, some running on multiple OS platforms, but most of them are confined to a specific one due to hardware and library constellations. In general, it makes sense to run the server on one specific machine, since the server has to connect to some physical device. Different ways of connecting the actual device are handled inside those servers. Additional servers can easily be implemented by using the existing servers as examples. The control for the vestibular simulation running on Windows95 connects to an analog card with specialized library from the manufacturer.
Stereo vision is possible by using two machines which synchronize their output.
The force feedback steering wheel control runs on Linux with the help of an analog card and a library from the LinuxLabProject. It is currently possible for Linux to control up to two joysticks at a time via the game-port of one sound card.
