I would like to start adding videos to my website, but I am paranoid about people stealing them!!!

It seems the solution might be "streaming" the videos instead.

So, what do I need in order to "stream" a video on my website?

To me, "streaming" means "sending packets of data of my video" versus "letting Users download my entire video as a file". (I am not talking necessarily about "real-time streaming"...)

My fear is that to do this will cost a bazillion dollars?!
