(TES, March 2): yes, the rash of proxy bypass sites are a huge headache, and "blocklists" become out-of-date in minutes. But cost is not prohibitive. There are products on the market that are priced to make them available to a wide range of educational institutions.

But things aren't all bad. EduGeek (www.edugeek.net) is an internet forum set up by School Techies for School Techies. As an ICT resource it is second to none and if any TES readers have yet to visit it, then they are missing out. Points under discussion range from virtual learning environments (VLEs) to security to hardware and back again.
