Parental controls - not an Apple thing

I have to limit the kids access to Google Video. Limit, as in, eliminate. Alas, Apple's parental controls are mediocre in 10.4 (better, supposedly, in the now delayed 10.5). If you allow access to a domain in Safari, you allow access to all. Apple's Airport Extreme has NO parental controls, my ultra-cheap DSL router has more.

I wonder how old Jobs kids are ...
