Hi,

I've looked a bit at this already, but would not mind if someone else 
picked it up. The main issue will be the case where you have both an 
activity and a service running with Qt, and either of them (or both) can 
be active at any time. For your use case it sounds like you will only 
have the service running in the process, which means this will be more 
straight-forward, I think.
