I've installed the PGP thing from Armynet on my personal laptop with the whole disk encryption thing and it runs just fine. Whilst I know we are not supposed to have restricted work stuff on our personal computers, it appears that as we are all being given access to a free copy of PGP, the 'system' is accepting the reality that we will do some work on our own computers (even if it's just report writing). I still use Truecrypt for encrypted volumes on removable drives. I agree that it would be useful to have PGP on DII so we can more safely send 'unclassified' (but still sensitive) work stuff to our home computers securely, but DII is so tied up in contractual red tape that I believe that this is never likely to happen.
