This is a while old, so hopefully not big issue with necro'ing this up.
I stream (twitch.tv/Moshcrates) just about on a nightly basis, mostly Wildstar (Ordo raids) but other games during the day and off nights.
We have two other streams as well: Jai (twitch.tv/dead_and_afk) and Malus (twitch.tv/Lekitor). They stream off and on during raid nights. Not sure of their official schedule.
I believe one or two others in the Wildstar chapter are also interested in streaming, so we are helping them setup their broadcast settings.
I currently use xsplit broadcaster to stream and have a whole slew of stream specific devices (AT mic, hauppauge stream box, secondary laptop to stream from). Happy to answer any questions or help others setup their streams as well.
Also to follow on the Ordo team topic, that would be pretty sweet to get a team together like that.
