If you want an easy solution working out of the box, check Ustream
(
http://www.ustream.tv/)
It provides live streaming with an associated chat room but also allow
you to record and store your videos, like youtube does.
I don't think you can setup a fee system, but I suppose you could
embed the video in a webpage with a virtual board and ask or fee to
acces that webpage.
