BattleTac - GPS tracker for airsoft and paintball

BattleTac is a GPL licensed live GPS tracker for airsoft and paintball Military Simulation. Users can track each other on the map using mobile phones and custom hardware.

The J2ME, Desktop(J2SE) and Windows Mobile versions are powered by the Nutiteq lib and we plan to release a BlackBerry version based on it too. (Note that the Windows Mobile version is integrated with PhoneME feature so it is a full featured WM application but inside of it runs j2me and nutiteq)

The Nutiteq lib works great for us, we are really satisfied with it. We have added a small feature too: the tile image processing hook mechanism for 'night mode' tiles.
