WiFi to GPRS gateway
If you are located in a place without internet connection the Neo should be able to act as a WiFi access point and route this through GPRS to the Internet. It will probably make sense to make the access point not open for everyone.
The access point software can be copied/ported from an existing Linux-based access point (e.g. [http://en.wikipedia.org/wiki/DD-WRT DD-WRT]).
For provisioning of access to the WiFi "hotspot" network, the open-source access controller [http://coova.org/wiki/index.php/CoovaChilli CoovaChilli] (based on ChilliSpot and actively maintained) is available. It's used in most after-market hotspot firmware and networks like [http://www.fon.com/en/ FON] and [http://open-mesh.com/ Open-mesh.com].
