    This will require special scripts to be written to distinguish
between gpg signed packages and pgp signed packages, and to
automatically call the correct program to check.  If they get written
before anyone attempts to implement this, I doubt I'll mind the new
addition.  If I have to write them myself, I'm going to be annoyed.

    You can't use an existing PGP key to sign a GPG key, not in the
usual fashion anyway.  I suppose I could uuencode the GPG key output and
sign THAT with my PGP key.  GPG however doesn't support the necessary
encryptions to handle keys with PGP signatures on them.  That leaves
room for (admittedly this is highly unlikely) substitution attacks
between the time the signature is checked and the GPG key is put on the
keyring.
