@Rico:1. for now the resource requirements of run tracker apps are unique enough that you're better off building them as foreground UI apps that run under the lock screen. since music can go into the background with Mango, this means you can still have a run tracker & audio playback running predictably & simultaneously.

2. for background transfers in Mango, we actually provide a built-in service that will handle the upload/download for you. take a look here:
