Thanks everyone for the overwhelming response! I read every single comment and will plan future releases around them. Forgive me for not replying to every single one of them... I want to spend more time on the app . Some comments though:

I want the app to be sports-generic. I'm (almost) as big an ice-hockey fan as a football fan. So far, I have found no data source for other sports (well, haven't really looked either...), so it might become a football only app anyway...

The choice of 'live' data provider hinges on two factors:
1. Legality of use. I know there are loads of places where I could parse information such as 'live scores', but if they don't explicitly allow me to use it, I won't.
2. Cost of making use of it (at the moment, I only consider free sources, but that can change in the future). The ones I have contacted charge EUR750 a month and up.
There are four ways around that.
A) Find a way to get 'live scores' from SoccerDB. I know the data is there...
B) turn this into a paid app (that'll be my last option, the way I look at it now. Maybe only pay for a 'live score' version of it?),
C) Find other means of funding the data feed (e.g., ad links, but I seriously doubt I could ever get close to the amounts necessary).
D) Someone makes a huge donation

As for the issues with the app, I think I have to pay some serious attention to the 'auto-shutdown' issue. Without solving that, it will never get acceptance by the larger community and no feature I add will ever outweigh that... The problem I have resolving it is that it happens when the app is doing absolutely nothing, so I assume it is some resource issue... I have some (small) hope that it is due to PR1.1/Qt4.5, so maybe it will be solved all by itself with PR1.2, but I'll look into it anyway.
