Thanks, David. That should be good enough for those of us who want to 
generate oversize keys for some reason.

Actually, I agree with the criticism of these large keys, but I have a 
correspondent who refuses all encrypted communication with keys 
smaller than 7680 bits. Paranoia or eccentricity - I'm not sure. I 
have a large RSA v4 key created with a hacked PGP version, but I'm not 
happy with it because it has a v3 signature on the subkey, which 
doesn't seem too reglo for my taste.

Salut,
Maxine
