I looked into this a while back, they work by having a driver which hooks into the graphics system that is writing to the frame buffer, compresses the data and sends it out over the USB port in a specific protocol. Unfortunately the standard drivers of this only exist for Windows and Mac. The Touch is running Linux. There has been some attempts at doing this for X-Windows which is how most desktop linux systems do their displays, BUT the Touch doesn't use X-Windows, there is a different graphical layer that writes to the frame buffer. Theoretically its possible to add these calls to that system, but it would be a lot of work. It might be possible for a process to read the frame buffer itself and send that out the USB port, that would actually be simpler to program, that would take a lot of CPU resources in order to handle things that change rapidly. Not something we want happening on our resource starved little machine! So while an interesting thought, a USB display is not going to be something that is easy to implement for the Touch.
