Due to the potential for namespace clashes, you *must* have a single
central organisation to manage the localpart namespace. MX records can
also only route mail on a domain basis, and not by localpart. Again,
this tends to drive centralisation.

I would probably be tempted to just contract the whole lot out to a
third party that is not involved in your internal politics, including
maintaining a localpart registry.

The third party can then make a commercial decision as to the best way
to design the network is an complicated geographically load-balanced
cluster, or just to waste bandwidth and take a simpler system. Unless
they've got somebody CV-polishing, KISS will probably prevail as
bandwidth is cheap.
