I've been working on a unique idea for a site that works off using video/rich media as a medium to share information. The one true problem I can see with this is hosting this stuff, and how much it is going to cost me in hosting costs. This idea in theory works really well so I think with the right know-how marketing wise, I could profit quite well from it.

So my first question on the subject. What is the best way of having moving visuals and sound on your webpage. Preferably with the ability to watch it on the page you're downloading it from, like Google Video or something.
