Any reasonable way to bootstrap this off DNSSEC and dynamic DNS in the in-addr?  More complicated than DANE, but if the key distribution is the hard part, and DNSSEC solved that, I'd rather do the hard part once and get the benefit of it for multiple other protocols, rather than reinvent the wheel each time.
