This would be the diffserv paradigm rather than an address selection
paradigm. Do we have enough information to make this choice at this
time?

Yes! Can we all agree on this?

The application probably wants to include some additional information,
such as the type of service that it needs/wants. Also, we may want to
consider including a name space or address family identifier. That would
make using IPv4 and IPv6 addresses as identifiers more easily backward
compatible and knowing the nature of the host name makes selecting the
right name to address mapping service easier.
