2much.net is just a configurable white label where you can sign up your own models.
you DO NOT have access to the source code, or even the servers. you are tied to 2much for life.
www.CamScripts.com is a basic solution, full PHP script for $200
they have a nice viewport with transparent chat window over the video.
all the others available are simply terrible!
there's an ok $5000 flash script, forget the name but no source code.
