The live-trial of the Australian government’s ISP-level Internet censorship scheme is due to start in a few weeks. BanThisURL has posted a nice analysis of the test framework, and a bit of background for those unfamiliar with it.
My favourite part:
A point is made about formal circumvention testing. It falls short of trying to gain access to the ISP’s network, and … states that a number of techniques that could be used to circumvent the filters will be tried and the results recorded.
I can think of a couple of almost-foolproof techniques off the top of my head. I suppose an effort could be made to block anonymous proxy servers, but I wonder what might happen when the Australian government finds out about SSH and VPNs.
