That... is such an awesome idea.
Valve's becoming more of a scary beast if they haven't been already. The best team based shooter (arguably) is free to play, the next DotA, with triple-A VALVE-quality polish, is free to play with everything unlocked... including a free spectator program to watch tournaments on in the highest of definition. Steam's gotta be earning them buckets upon buckets of money... the buckets being made of gold, of course.
Scary as that is... spectator program is awesome. I'd use it if my computer did things... and also I guess if I could get commentary over the games like at a real event.
