Just like pimpin', streaming ain't easy. There's only a small handful of companies who know how to do it REALLY well, but the prob is: $$$$
Rule#1: Never use the hotel internet - always pay an outside co (Verizon) to install a short-term dedicated T so you're not competing with hotel room internet porn and youtube
Rule#2: Always use a tier-1 hosting provider. Ya know, that's been my steadfast rule forever, but after seeing how the president of UStream personally called the TAR guys in Louisville to ensure everything was OK with them, I was really impressed.
Rule#3: Have the right equipment
It all comes down to $$ and even then, you're praying something doesn't go wrong with your internet connection (which is out of your control - even when it's dedicated). The bottom line, unless there's a big time backer, these pool events will never be streamed 100% of their capability.
All I know is the Dragon site looks really nice. They just lack knowledge.
My heart is always with TAR - anything i can do for them, they got it.
