TCP connection over GPRS between Openmoko and Notebook

[Christophe M]

That's a simple/client server communication ...You will just have to open a
port on the server side nat to route it to your server ( even if you use
openvpn, ssh, ... you'll have to do it )
A second solution, if you can't translate a port in the nat is using a third
computer reachable from anywhere wich "organise" the transfer, both
freerunner connect at this third machine as client and the machine make the
transmition.
Protocol is at you convenience, making a client/server in  Qt4 isn't
difficult and is well documented ( if you need help, you can contact me )
