NMEA. Named after the National Marine Electronics Association's NMEA-0183 
standard.

The "Garmin" protocol is a "de facto" standard, but a lot of free & non-free software 
interface it nicely.

BTW, their latest OEM sensors like the GPS 16

look very cool to me. Would allow for some nifty "Netstumbler in a box" designs. :)

I think that's more like 15 ft, but that depends a lot on weather & number of satellites 
over the horizon.

Well, we had that (=NetStumbler+GPS) running last Sunday when we were testing 
the waters (literally) under Miko's roof, so I guess the only part we're missing is the 
definition of the "target areas". ;)
