I use Hal Finney's 'Chain' a lot: it is an easy way of automatically building a remailer chain. But it won't PGP correctly with the Usura and the Flame remailers because these two have e-mail addresses that have changed and/or are different from the addresses specified in their public keys (Usura, for instance, is now <usura@replay.com>, but this is not the address given in its public key ID). Is there a way for me in PGP to edit and update the information contained in the public keys of others? I would want to add an "also known as" line for 'Chain' to spot. O.A. <assets@alpha.c2.org>
