If you want to do your own shows on your own site, hit me up on ICQ I have some custom developed cam solutions.
Here's our Cam Girl site called Camsturbate.com
http://www.camsturbate.com we are developing a flash community on there and some other cool things.
Really anything is possible now, just make sure you get in with a company that knows how to work with Flash, that is if you want something custom.
Here's a example of a "canned" live cam solution script
http://www.flirtinglive.com this is ours too, it's not bad but we wanted something more customized.
Contact me since I need to know how you want to do the live shows, one by one, from a live chat area?, customers to buy minutes? .. there's quite a few ways to go.
