Brpilot: what I'm getting at is that you, as a school, will be WHOLLY responsible should something be allowed to be viewed in school that shouldn't do. No filtering system is perfect and kids will always find a way - and they'll find it quicker than any of us can close it. With that responsibility, when something goes wrong rather than you being able to say you took reasonable precautions, people will be getting sacked. Bare minimum you *need* is IWF filtering at the ISP's end.
