That's good; I've not done anything with protocol buffers, so wasn't aware it was that simple. > > In particular two additional identification types: > > - GnuPG (obviously) > > It's not obvious to me, incidentally.

Sorry, I meant "obviously" in the sense that "obviously that's the other one that everyone will want". The web-of-trust as a universal identity mechanism is, I agree, not useful. However, as a localised, smaller-scale identity verification system it's used by every GnuPG user. You become your own certificate authority. For example, I've set up my whole family with GnuPG; I've set them up to trust me to authenticate (and I doubt any of them has ever added anyone else). Then I take on the responsibility of signing all my family/friends keys and they don't need to worry about it. There's no reason that a small group of companies wouldn't do exactly the same sort of thing. > Your case of a small business is a perfect example of people who won't > be using GPG. If they don't want to buy an SSL cert, they can just as Bear in mind, I was using that example as an example of a hash protected in a GPG envelope, not a GPG-signed invoice. People who've already got their GPG system in place will appreciate being able to leverage it. > well put a reference number in the memo field or a "Hey Bob, here is > the bill we discussed". The payer does not get the multi-factor auth How can they put a hash of an invoice inside the invoice? In my "hash mode" invoices, it would be a random number (or possibly specifying the hash algorithm) then the SignedInvoice would simply be the original invoice + hash. That hash would then be reported via some secure channel outside of bitcoin's domain. > protection so if their computer has a virus, they may be hosed.

The payment is performed via normal bitcoin mechanisms isn't it -- multi-factor or not? This invoice system has one primary job: to ensure that the target of the payment is who the payer thinks it is -- that's not affected by multi- factor methods of protecting my wallet.
