Our staff have always had the same access as the kids, this is done via RM filtering and our own ISA server, for one thing it saves the hassle of teachers planning a lesson around a web site only to find that the kids can't access it. We've recently had a few teachers wanting us to get them videos from youtube though so we're now using a two tier approach on the ISA server - there's now a staff only 'allowed' list of sites that are blocked for the kids, at the moment there's only youtube on it but it may grow in the future (but it won't be including bebo, facebook etc)
