Problem:

There is no gtv, demos take too long to come out from big events? Casting is inconsistent and costly.

Solution?

Code in an FTP interface into quakelive which uploads the demos to a quake repository after the game has finished.

That way, even without coverage, as long as the venue has net connection (it needs to anyway), the demos will get uploaded to www.quakelive.com/demos

Come event day a simple bit of XML showing timestamps of demos, player POV etc.

You could have ever demo and config within 2 minutes of the game ending and once its setup once, you would not have to worry about it.
