I use 3 streaming webcam sites for my member shows.

http://www.yourdailycams.com/ Streams in HD & your members to get access to all the other models using the network. Members can also tip models during shows
Sign up for a Streamate affiliate account and email them asking to set up the sites to run external site shows.
They'll give you an iframe link. The models will be able to do members only shows free for their members. They can also do privates and earn commission if their members buy shows from other Streamate models.
