I put a new version up here.

It has the code to deal with gpsd, but the empeg doesn't have the loopback network interface so it is not active. Also changed serial port handling a bit to allow for other GPS protocols besides NMEA.

Immense thanks to dbrashear for putting a real Trimble on my desk, as soon as I get that serial interface built I can test TSIP and TAIP, the Garmin protocol has been tested already with an Etrex Venture.
