Recent forum thread was asking if its possible to have a printable certificate to prove a disk is encrypted.  This got me thinking, in a Universal Server environment, its easy to prove if something is encrypted incase it gets stolen, which is just as powerful as the encryption in itself.

Can this be transferred across to unmanaged PGP Desktop clients?  Either through some cloud based system whereby discs are encrypted and confirmation of this encryption is stored online for retrievable for proveable deniability?
