I'm all for coming up with an open alternative.  Sounds like a fun 
discussion for DCC.  Use the Speex codec or get the Ogg guys to come up 
with something, add data services with some MEANING assigned to them, 
carrying something a little more creative than NMEA sentences, make the 
protocol flexible an extensible but not hugely complex... and maybe 
start thinking about something better than FM and GMSK.  COFDM, maybe? 
I'll leave that part to those with more RF background.
