That would make it so much easier to add a watermark and post the video illegally to a tube site.

I don't think our models would appreciate this ...

However, if the recording was kept on site with the customer entitled to re-streaming that recorded private show with no browser caching; it would be OK ? no less secure than broadcasting the original private show anyway ...

The problem I see is the models complaining that the customers can rub one out without buying a new show.

The fact that you are overlooking is that many good customers spend money in private with models for more than just sexual exhibition ? they seek the personal interaction and friendship with the model. A "private show" might include a lot of talk and not be so exciting to see over and over ...
