Hmmm. I misspoke, because I've definitely used Google Video, but I also wasn't clear with what I was trying to say.

As far as I know, Google doesn't allow porn on video.google.com, so it is not subject to 2257, it simply removes any adult content that shows up.

And it's weird, but if you look, Google recently changed video.google.com into a search engine... it now returns results from Google Video, Youtube, and a number of other Youtube clones.
