I've been watching a lot of hulu.com video's lately. Ok, so they are embedded by with ads. Not a problem. They do everything else right: high quality streaming video feed, they allow embedding, there is lots of good content, it works on multiple platforms (unlike siverlight), and the ads are not that intrusive. And they are pretty damn secure too - I've been trying to figure out if there is any way to download them, and I've yet to figure it out. Good job so far!
