This (in the New Scientist and which was posted last Saturday on the Libertarian Alliance Forum) is really a story for expert Adriana to comment on, but it sounds good on the face of it.

Computer activists in Britain are close to completing an operating system that could undermine government efforts to wiretap the internet. The UK Home Office has condemned the project as potentially providing a new tool for criminals.

Of course it could just be that the Home Office is writing it, and wants to round up lots of would-be secret persons into one pen, so that it can snoop on them all with greater ease, and save itself the bother of trawling through the emails of all the people like me who don't give a prune about secrecy.
