I guess my main point was that I didn't mean DNS when I said name,
and that symbolic-name->ID mapping and ID->mapping are independent.
A specific implementation could, of course, us DNS for both, and
this, of course, would impose additional requirements on DNS, as
it would need to be dynamic enough to allow initial connection
establishment to mobile hosts...

We'll also need to update the [whatever] system that helps
the initial name->address resolution so that new connections
also succeed.
