Mouse & keyboard support for headless platform

This may seem like an odd request, but is it possible to add USB mouse and
keyboard support for a headless device? It looks like I can do it with null
display device, but that causes some problems (pulls in lots of extra code
which isn't used, applications may think that there is a UI to which they can
send messages).

Our device is remote from the display, but may act as the connection point
for a mouse & keyboard. We take input from both mouse & keyboard and pass it
over a network connection to another device which mimics a USB mouse or
keyboard to some other host system that ultimately drives the display.

Hope that makes sense. Any suggestions would be appreciated.

You may not need everything in a headed device configuration, but you need
at least SYSGEN_MININPUT and maybe more (for the mouse). You'd have to just
try it and see what happens. You'll have at least the minimal GWES stuff,
the message queues, etc. It might not be worth too much fooling around...

If you have to provide some sort of remote UI, did you consider the
idea of "hiding" it inside the display driver?
