Originally Franson GpsGate simply enabled GPS NMEA 0183 data flowing into a PC or PDA serial port to feed multiple programs simultaneously, but now it’s something of a software Swiss Army knife. The latest 2.5 version works with all sorts of I/Os like Bluetooth and the Internet, supports multiplexing and data logging, and lets groups share their location data over the Web. Any member can see where his/her buddies are at GpsGate.com, and copacetic programs like Tiki Navigator can plot them right on your charts. $30. Franson, 011-46-8-612-50-70, www.franson.com
