Interesting Startup Idea: Photo Sharing (etc) for Couples...

I'm guessing most people would be uploading video from their hard drive or camera, as opposed to having the site capture it live via webcam, so that means that the media still resides somewhere besides the online site. I'm not sure people would actually delete their hard copy, and thus there'd still be a risk of a sex tape scandal.
Let's say that you can solve that problem, perhaps there's a solution out there that I'm not aware of. You still have the ability to record it at the same quality it plays using CamStudio or any other kind of screen recording software.
Ok, so let's pretend you've managed to block any kind of downloading, any kind of screen recording program and any kind of site vulnerability. If I were the kind of person who wanted to download photos to start a scandal, I'd just take a picture of the screen with a digital camera. Sure, the resolution might suffer slightly but with a tripod and a little trial and error I bet I could get them pretty nice.
I like the idea of being in control of when they're deleted from the server or having a time limit, I just don't think it's possible to control where the content ends up.
