Worst case you only crash everything on one Unit with multiple networks, but it will cost you more in hardware. We rigorously separate our units, but then we're a nuke. It's still a good idea. My best advice for mesh architecture is to make sure you can tolerate a complete failure. Avoid ZCPs like they're a bill collector.
