Wonderful idea!

I'm experimenting with making this easy to use in Gnus.  Would it be
possible to make it possible to specify the -N stuff through gpg.conf
too?  That may be simpler for users with old MUAs that hasn't been
updated to support adding that parameter.

Meanwhile, something like this seem to be what you need in Gnus:

(setq pgg-gpg-extra-args '("-Npka-address at gnupg.org=jas at extundo.com"))

Thanks,
