Good timing! I'm at a hackathon right now working with a group to come up with a standard for adding Bitcoin addresses to OpenPGP keys. You're correct in thinking that doing so with standard Bitcoin addresses is a privacy problem, however we can also define new types of Bitcoin addresses that address the privacy issue; stealth addresses can handle the case where you want to pay someone without a formal payment request, and integrating OpenPGP into the payment protocol handles the scenario where you want to send or pay to a formal payment request.

Incidentally on my todo list is to come up for a reasonable standard for taking X.509 certificates and using them to sign OpenPGP user IDs. Essentially the certificate authority is then making the statement that a keypair is authorized to sign on behalf of a domain-name, and in turn that keypair signs that the email address on the user ID is correct. It's a best of both worlds option in the same spirit of keybase.io -- 'peter'[:-1]@petertodd.org 0000000000000000f4f5ba334791a4102917e4d3f22f6ad7f2c4f15d97307fe2
