You're right that the services in that case were stateful, but the
stateful-ness of them had nothing to do with using separate topologies. The
reason that was done was to completely separate out "traffic for data set
A" from "traffic for data set B". Since said trafic could have potentially
been gigabytes of data, this seemed like a good idea.

I appreciate your concern for the big picture, but I'm proposing to replace
the use of a hack which people are actively employing (calling bind X times
in a loop) with a robust and simple solution directly supported by the TCP
stack; why do you think my proposed solution is a hack?
