Yes.  Put "encrypt-to (the-adk-key)" in everyone's gpg.conf.

Of course, they could turn around and take it right out again.  Unless
you have pretty tight control over the environment, ADKs or
encrypt-tos are not foolproof (and that applies to both PGP and GPG).

As I said before, note that this isn't safe because of the crypto
math.  It's "safe" because you can fire people who don't do it.
