Pan's one lacking feature for me is that it provides no mechanism to verify
GPG/PGP signatures, a la Mutt (just a simple indication whose key was used
for signing and whether it checked out or not.) Of course seeing as the
primary focus of Pan is newsgroups decrypting and encrypting messages to
newsgroups is not essential at all.

KNode implements this, but hangs the entire program if the verification
takes a long time. It should not block at all if one wants to make it
better for Pan ;)
