Just set-up a small e-store with a few custom designs, all assembled by hand(!) in Canada. Two Leonardo-compatible boards, and a bunch of other boards/shields.
or soon; http://www.cal-eng.ca
I've also added a fairly comprehensive tutorial on the Leonardo HID mouse and keyboard routines. By poking around USBAPI.h, I think I've iced the mouse functions, but I have yet to figure out the syntax for using the KeyMap/keyReport, to allow the use of modifier keys (I think it uses keyboard.print() somehow, but I just don't have enough info! Any ideas?) See: http://cal-eng.com/?page_id=579
