It shouldn't cost much, if you already have machines on networks with decent bandwidth. Then again, I know all "cloud" things are meant to extract profit once they become popular, and video hosting could easily go from nothing to something quickly.
How many terabytes of storage and how many terabytes of transfer per month are we talking about here? This could easily be started on resources that some of us already have and can be scaled up later, rather than using "cloud" and worrying about some huge bill at some point.
