I have to agree with everything Jacob said. We've been runing a live gay cam and voyer site since '96, and its a huge undertaking to even manage something like this on a dayly basis, not starting new.
The important thing I think is the point about the webmaster/member retintion. It is absolutely the best with the live/voyer type content. What Jacob said about members being on the site for a large number of years is true, and not all that unusual.
So if it's a choice, deffinately look into leasing some live plugins.
