I want to know how I get my footage from a remote location like out on the street up onto a stream site like ustream - basically how do I get a remote internet connection powerful enough to stream video.
UStream, BlogTV, Justin.tv and Stickam.com (My suggestions is Justin.tv).
You're going to need Flash Media Encoder and a decent internet connection, at the very leaset DSL, perferable Cable. T1 is actually slower than a Cable connection.
You can probably feed the internet connection out into a router (or a second router) that you'd have outside with you, but you'd need somebody to monitor the computer for encoding.
You also going to need some kind of capture card. Your best option is one of the Osprey Cards for ViewCast.
