Interesting that the SMH plastered a story about the web filter plans across the front page of the print edition but buried it on their website.
The story is a first order beat up because it doesn't address the filter pilot as proposed, but talks a lot about a range of issues that are not being considered. The most significant of these is the idea that this is some kind of dynamic filter - which it is not.
In fact "filter" is the wrong term. It is better called a "clean feed" as all it is designed to do is block access to specific web-sites.
People in the know actually tell me that the conclusion of the report leaked to the SMH is that a filter that just attempts to block access to a blacklist is entirely achievable, while relatively easy to circumvent.
