Hi,

GPSD is usefull for dealing with many kinds of differenet devices etc. 
In case of one specific GPS device in GTAxx, full potential of GPSD 
cannot be utilised. But GPSD still have few very usseful features, one 
of them is data export trought socket/network. This way can be GPS data 
easilly accessible by other applications (eg. experimental application 
in python or tunneled trought network into PC).

I have in past did some dirty hack wich create socket and when someone 
start reading it QWhereabouts starts GPS and act as proxy (and close GPS 
again when noone reads anny more). This code is not usable now, but this 
feature might be ussefull for hacking.

Pinky.
