Video presentation that cannot be downloaded ?

We are putting together a video that we want to promote to our list and we want to be able to run it for just a limited time with links to special promotions etc. We actually do not want it to be shared or downloaded.

How can I setup a streaming video that people cannot download? We don't anticipate massive simultaneous views but I'm not sure if it would work hosted on our regular server account. (running time will be about 1.15).

(When I say 'cannot be downloaded' I know that really tech-savy types can find a way, I mean for most people

Try vimeo pro and make the video private only to your website so that no one can embed it or download it
