I don't understand what problem this is intended to solve. Bad guys can look up PGP keys just like good guys, so all this would accomplish would be to fill your inbox with signed spam. Perhaps it would be useful to make a section of the ASRG wiki in which we describe the difference between the spam problem and the other problems that people confuse with the spam problem, such as the introduction problem and (more familiar to cryptographers) the authentication problem, the interception problem, the non-repudiation problem, and doubtless others that I can't think of just now.
