Streaming doesn't automatically protected your content, it at best obscures it a bit.

Flash has options for encrypting content as it's sent, not sure if that's been broken yet or not. And if someone -really- wants the content, they'll get it anyway.

Exactly, in fact nothing you can do can protect your content (well short of not letting them view it). As anyone can get a screen recorder and capture it.
