PLEASE use Twitch or YouTube for your livestream. Everything about FIRSTWA's streams are great except for the fact that they use Ustream, which has almost no customization in quality for the user, something that is a pain for people with limited data plans like me. They also have a lackluster chat and almost no way of watching past streams.
While im on the subject, find someone that did A/V for FIRSTWA. They are a great place to start. The DCMP last weekend shows how well they do, with two feeds for Full Field only and a Main stream that had the cool camera angles and such. They can also give you a rundown of what exactly they used (they also did a webinar on it, and its somewhere on their youtube.
Ill try and link it here found a whole page on it
