This thing is awsome. Crashed it couple of times trying to download LOS ANGELES @ 2. . Now i'm doing chunks. It's just a pint to input those ccordinates every time you go in.
I have a USB GPS mouse, got it few years back. Any chanse that is gould be used. I believe it can use prolific 2303 driver (in-kernal driver on 2.6), but don't know what you would need to change in you app to support this interface. The GPS unit is BU-303. This would be nice as I have an setup in place from old Carputer (GPS and Powerd USB hub) wich would work greate with this.

But, great work non the less. Can't wait for V2
