As I'm setting up a similar infrastructure for a mobile application now, this project interests me a lot. I have made some different design choices so it'll be interesting to compare the benefits of my approach against choices made by the usergrid team. I'll dig into the code more deeply and join (with contributions) were I can. Definitely a good addition to the apache incubator!
