Things would get much better if a PGP 2 version with support for CAST5
would get more into use. We can't officially support IDEA for patent
reasons in GnuPG; the next release comes with a --pgp2 option to
bundle all the options needed for pgp 2 cmpatibility and furthermore
you will get a warning if a message can't be encrypted in a PGP2
compatible way.
There is a pgp 2 version by Disastry (http://disastry.dhs.org/pgp)
which support all OpenPGP defined ciphers.
