I've hacked out perl scripts that re-mangled data into APRS objects
and sent them to xastir via a server port. This looks like an ideal
candidate if you had that compass and a GPS.

I've also seen 3D compass solutions (using 3 axis magnetometer / 3
axis accelerometer sensors) on the raspberry pi. you could probably
take the 3D compass solution, ingest the strike report and spit out an
APRS object, either over an IP connection or out a serial port as if
it were a TNC.
