I think an 'opt-in' page for it would be cool.it wouldn't be too crazy to implement - you just have a simple form that preloads your username into the user field (unable to change this), and you paste your public key. You have it correlate to a directory page (you would probably need one page per letter of the alphabet and 1 for usernames that begin with numbers). On the page would be hyperlinks of each username, opening up a page with just the public key there. Kind of like a phone book for PGP.I don't bother with the PGP forum posts because there are so many usernames throughout it with no real rhyme or reason it take ten minutes just to track down someone's username (and that's IF they are posted there).Just a thought. SR Phonebook or something like that. Only for people comfortable with throwing their public key up there.
