If that's the case though, why not keep DNS for now, especially for the initial handshake?
Then, similar to HSTS, the browser could remember the mapping and use the DNS name as a pet name for the target.
Another alternative would be to use "phonebooks". One could trust a few trusted websites for the initial handshake: "oh, just google battery horse to find my blog". Or: I'm linked on John's blog. That goes well with pet names, but is a bit more involved.
In any case, as long as the underlying identifier is secure and unique, you can just share that trough other means (links, Qr codes, messages, etc).
