I'll think about that. The hardware is not trivial (it uses two switchers
to generate adjustable programming voltages etc) and connects to a standard
RS232 port. I had a bunch of PCB's manufactured, but I've run out of
populated boards (empty PCB's are still available).

It's a 18-pin package, up to 16 pins can be used for I/O (one of those
is input only).

Yes, at http://www.microchip.com/
