openpcd integration with RFIDIOt

[Milosch Meriac]

Dear Adam,

let's move this discussion to the development list, because other might
also be interested in a more convenient script engine and a Serial
Termminal emulation over USB for OpenPCD (compared to the existing
binary USB interface in main_dumbreader).
I already have released our OpenBeacon USB reader:
http://wiki.openbeacon.org/wiki/OpenBeacon_USB
with a serial CDC serial port console emulation over USB - works nice
even on Windows without drivers.
I will get a simple version running before this years Chaos
Communication Camp 2007 in mid of August. Maybe one of you guys wants to
meet us there on the camp to have some nice firmware hacking sessions.

I totally agree - there will be a consistent API wit result codes which
allows you to process even replies to unknown commands.

Warmest regards,
