Interesting! We have a situation where we have two networks running on
the same switch. Our system administrator has mentioned that it's the
only slightly strange thing about our network, and though it's
completely legal, it's probably not very well tested...

Yes, of course!
Are you worried about breaking compatibility because people need to run
multiple versions simulataneously? I suppose that would be critical if
you were trying to upgrade a large distributed system with zero downtime
(i.e. one system at a time), but other than that, it seems like a Very
Bad Idea. :-)
