Maybe IP address portability is more analogous?  In the ARIN region you
have to be an "organization", you can't be an individual, to obtain
your own numbers directly, but otherwise you can announce prefixes from
practically any upstream, and even transfer it to another RIR, while
maintaining global uniqueness.

Maybe this isn't as convenient, because a phone number is associated to
a specific voice service whereas IP addresses can be associated with
practically any application.  Is the abstraction and flexibility
that makes IP address portability just less user-friendly?
