Re: Streaming
Well, in regards with providers, most every one of them has two clauses that shut down streaming.
a) Most usually have a 'No pornography' clause which is defined usually as 'What is the primary point of the game?". Note, some games get around this, but they're on a case by case basis.
b) They also have a catchall clause which amounts to 'If it makes us look bad, we're going to shut you down'
Some will also try to nail you on copyright grounds.
That all being said, with a couple of the setups (Youtube and Hitbox.tv) you can list a channel as private. In Youtube's case, you can force login/passwords as well.
Ustream was used previously for some Japanese h-game players for a couple of specific games as well.
(I was thinking about it myself and did a lot of enquiry, but a house fire ended that idea. I'm in cleanup mode (Stuff survived but the residence is a writeoff) but if you want me to answer questions on how to do it, PM me and I'll fire over all the notes I have on the subject.)
