The first link seems to only give information specific to those programs, I don't see anything useful to me. (EDIT: maybe that address mentioned in the first one might be useful)

The big problem is if it's possible, I don't know where to stream to. There's no mention of an IceCast server, an address for UDP, or anything, as far as I can tell. It just tells you to download their program.

EDIT: Actually, I don't see how to even create a live video "post"...
