i haven't really been following along, but there are some ic-ish bits in
the picture link (dtmf decoder/etc). given the age, i'd imagine that it
was doing something older than zigbee.

i bet if you convinced bunnie to do this as one of his ware-of-the-month
thingees you'd get a complete tear-down :-)
