I don't know if I should write in French of in English, just to be sure I'll write in English to make sure you understand what I'm saying :)
I've seen you wrote something on the OSM4Games GSoC Project. I'm really interested to work on something similar as I wrote on the page. The idea is more specific as I've been thinking about it for a long time. I'll be applying for this project as soon as possible. I've sent an email to Ian Dees about it and he thought the idea was good.
If you'd like to talk about it here's my email : mathieu.triay (at) gmail (dot) com
