I do. I can tell you that there isn't a tip system, however there is a pay per session module exclusive to wordpress (although I have no experience with that module).
Also, you do have the ability to save all webcam sessions of all broadcasters, but they aren't available to the end user as is. They are saved server side. You would have to physically move them to a publicly accessible web directory. Also worth noting, this does require an additional server software to operate, Red5 (Free), Wowza or Adobe Media Server.
Ironically, I am working with the dev to get a copy to demo on my site
