I've been looking for something similar for a while now but technology is
leaping ahead and the only similar things I can find are all Radio based
If you have any sucess can you post back with the details as there is
another sale here :-)
if you are interested in Radio instead there seems to be a good response to
the M$ HTPC combo KBD and Trackball..... i almost bought it but remembered
my morals :-)

Duct tape is one of the sacred triumvirate of the Most Important Tools in
the World. Use the Tool Triumvirate thusly:
1) If it moves and it shouldn't -- use Duct Tape.
2) If it doesn't move and it should -- use WD-40.
3) If it should sometimes move -- use Velcro.
