True enough. Harder it may be, because they'd have to come up with something new. Not however impossible. Likewise, serving up their video wrapped in Flash doesn't make it copy-proof either. Far from.

I can appreciate Hulu trying to keep content owners happy, but they must know that's a false security. TV episodes can be downloaded the same night they air, or earlier, elsewhere. In higher quality and at a faster rate. All that said, they'd be able to have much better security with their own software rather than relying on Flash through a browser. I don't however have any insight into what they're going to do with their own app.

I think the biggest concern for Hulu is what happens when they start charging for content? Much more significant than whether or not they'll move to serving video without Flash.
