I do want to clarify that I'm not suggesting that applications should vouch for themselves. Rather, I am suggesting that there be a set of certificate authorities which require applications to do proof of possession and then issue them a credential which is publicly verifiable.

Understood – I meant just that it’s then up to the applications themselves to conduct their own proof-of-possession, to exercise the routing system to reach themselves (at the time etc. of their choosing), versus having the peer who wants to communicate with them exercise the routing system. Of course the result will be some kind of token/credential that rolls up to a trust anchor, maybe a STIR-ish one; my point was more that we could profitably focus on who secures that token and what is secured in it, and then compare different architectures for distribution/discovery of such tokens.
