Hmm.. it would need a switch to switch between normal mouse mode
operation and multi-touch operation.
The multi-touch operation would need a modified mouse driver
I'm guessing. In the normal mouse position, there is no need for this
extra driver, but in multi-touch position, the USB device would have to
re-register as some other device so that driver can switch to
multi-touch operation.

Sounds doable :)

That is two projects needing doing - generic switch mode power supply
and generic touch to mouse converter.
