Nice article up on the BBC news website about the Cipher Challenge that's going on today: http://news.bbc.co.uk/1/hi/technology/7094881.stm ... I've not been involved in that side of things, but it's been interesting watching Tony and his crew running around the last few weeks trying to get everything put together (there was a huge amount to do on the reception/intercept side of things in particular) cheers Jules
