Yep. Rush has a two tier approach like that, and it appears to work for him.
TheSarahPalinChannel is on the TAPP network. The network charges the fees for the channels, collects the money, then pays the channel owner a percentage after their expenses are met. Members are free to repost any of the videos to Twitter or Facebook and anyone can watch them there. I would guess that very few of the videos won’t make it to Facebook or Twitter. The repost also contains the invitation to join at the end of the video. In this way, the videos are available free and it provides a source for new members. A member would not be able to link to the SPC site from another website like FR and have the videos available free. Maybe that’s something that can come later.
