How silly are you willing to be about the identity-exchange thing? I could, for example, give you my username on Nightstar’s forums, compromise of which would cost me nothing. You create an account there, send me a PM through that forum, I reply with some piece of information which you then repeat in reply to this comment, and (a secure channel having been established) I could then send you my e-mail address through Nightstar’s private messages.

Heh, that’s a little more elaborate than necessary, I think. I’m bdill(at)asu(dot)edu; it shouldn’t be too problematic to make that public.
