PGP 2.3 was GPL'd. There might be forks of that floating around somewhere
that still bear the GPL, if that will serve your purpose. (2.3 proper
won't work, because it uses v2 keys.)

Yes; PGP 2.6.2 used a different key format, version 3, which had a number
of problems with it. The IETF created a new, improved key format to
address a number of these issues. OpenPGP compliant apps all use v4.

Nope -- GnuPG has partial v3 key support, but does not generate them.

To my knowledge, there are no plans to implement it, because encouraging
the creation of more v3 keys isn't really the best thing to be doing.

Have everyone upgrade to an OpenPGP compliant application, like GnuPG or
Other than your suggestion below, not really. There are some utilities out
there that will convert a v4 RSA key to a v3 key, but I don't know how
stable they are.
