Foxy: you have had a good idea with your application. Congratulations. And good luck with your PhD thesis.
There is a system for speed cameras in Poland, embedded in a navigation software, which looks very similar to yours. It is called NaviExpert.

I've been using it for quite some time, and contributing to it, too. It seems to work fine. And it is embedded in navigation, like I said.
Cheers,
