I'm working on the GPS mobile tracker version of APRS Messenger over the 
weekend. All being well it should be ready for your trip.

Tx PTT will be on the existing com port and the GPS input will be any 
other serial or USB port. GPS input will be 4800 bd NMEA looking for the 
$GPRMC string.

I'll post information on APRSSIG when it's ready.

73,
