It is not in the callsign system itself, but once there is a directory that maps @alice onto a public key fingerprint plus a service from which a contact assertion signed under that key can be obtained, we can bootstrap to new messaging protocols that give us any desired communication properties very easily.

The reason SMTP email is so sticky is that all Bob has is the address alice@xxxxxxxxxxx. So Alice is limited to the set of protocols supported by example.com in the case of Alice and the least common denominator in the general case which is SMTP. There is no way to negotiate a service upgrade to OpenPGP over SMTP.

In my scheme, Alice can decide she is only going to accept calls from @bob and @carol. She can put @stalker on a blocklist that prevents him from retrieving her contact assertion, posting messages, placing calls, etc. etc.
