www.forensicsoftware.co.uk is the home version of filtering software that my work is starting to offer to schools and other council linked child support and care organisations that we support. For £25pa I can assure you it is very good at what it does.
In my experience kids are never too young to learn about respopnsible net use. At your kids age it is more about them being comfotable about coming to you when they come across something they don't feel comfortable about while online. The fire and brimstone route tends to be counter-productive in my experience, I have seen more then one school come a cropper as a result! And anyway your kids are pobably more comfortable about using a PC and the net then you, and they might suprise you in what they know and what they can do! I gointo schools regulary and see kids of 5,6 & 7 (up) using powerpoint, photoshop, flash etc quite happily, and scarily knowing far more about those packages then I do!
