Not exactly what you asked for but
Chaturbate has an embed that solo girls can put on their own site. You can either pass protect it and make it for members only or do free shows for your members while taking tips from both members and those browsing Chaturbate. If you're working directly with a model this is a great way to keep members happy while letting them make some decent extra cash to stay interested.
