I have an idea. What if make Quake Live LAN fully crowd-funded from twitch subscriptions? And of course only subscribers can view this stream and it will be streamed only by one streamer. For example $10k prize pool duel LAN tournament requires 1000 subscribers with $10-15 subscriptions. I don't know how many is twitch's fee and streamer work costs. Is 1000 achievable? I saw 4000-5000 viewers at twitch only while QuakeCon 2014 group stage.

I hope problem with only one stream (to have streams in other languages) can be solved by creating several twitch accounts and given login-password for streamers. So they can only stream without ability to change anything else (payment credentials, etc). I guess there will not be any pirate restreams because Quake community average age is high enough and if will twitch provides any tools to detect them and will prevent it quickly. Of course well known streamers, organizers are required and it can be held at some LAN party place like DreamHack. Surely first LAN can't be done by this way and needs some risky donate to have guaranteed prize pool. Without having this guaranteed prize pool only optimistic viewers will pay for it and very optimistic players(sponsors) will spend their money for this.

Is number of subscribers is the only one problem?
