I am beginning to invest my time in the openmoko world. I just ordered 
one and will start working on it next month probably. I am mostly 
interested in the GPS area. I am *very* excited by the prospects :-)

Your post made me doing some research about gpsd. In my opinion, the 
concept of gpsd is nice for desktop application but I am truly wondering 
why this is relevant for a handheld device where only one app is on 
screen most of the time. I am also not very keen on NMEA, very bad 
protocol if you ask me. The only sane and powerful solution is to read 
and decode the ublox binary format. I happen to know quite a bit about 
that, maybe I'll contribute a decoder...

By the way, I didn't know about Tango GPS until now, it looks nice for 
what I read on your web site. Once I come back from holydays and I 
receive my Gta2, I'll try it. Maybe I'll contribute, who knows :-)

I am involved in LyX development too ( so maybe I'll port 
that too :-)

Your two cents was worth enough to trigger my motivation :-)
