Safe Internet For Children New Startup

Found this site, basically it creates an "intranet" with a list of safe sites, and keeps your kids out of your file system and out of bad sites, and also gives them safe e-mail.

Made me think of the whole .xxx ordeal, I think this is a good idea for parents as an alternative to blocking, plus it keeps them from ruining your PC's OS by deleting files or installing viruses etc

The problem with a proxy or link service presenting itself as a walled garden is that it's still a bunch of third party websites that could have the content changed to anything. The only 100% safe environment is one where the content is duplicated and re-served statically, but that counts out just about any current 2.0 site...
