Also, there's a difference between keeping a copy of the key you use
to encrypt your hard disk (which in fact is a quiet legitimate reason)
and giving away a copy of the key(s) you use to communicate.
GAK is supposedly (ha!) used to restore lost keys. Can you give us one
example where you'd want to replay a communication ?
Never mind escrowing signing keys...
