The word is out that those guys in the Google group UK Government Data Developers have got it right with their clouding up the government data. Thats not cloudy as in murky, but the Amazon and other clouds.
I, of course have no idea about government data but this guy can tell you officially as he's been given a peek. Whilst a little curbing of the enthusiasm may be in order it looks as though there is light at the end of the tunnel. No reports on security yet.
