Audacity

Hello. I was wondering if it is possible to stream live with several girls from several cams at the same time, I guess it would be referred to as a "studio" of sorts.... Got a cpl twists - but are there cameras, software recommendations that you can give me? Does every camera need it's own PC or is there a way or type I can run several or preferably all (apx 7) through one PC (with my own dedicated server of course) PLEASE HELP....
