We can just use flannel for both these use cases.  One way to approach 
using flannel is that we can expect docker networks will always be setup 
the same way, connecting into a flannel network.

I am not clear on how to handle native Docker scheduling if a bay has 
more then one node.  I keep hoping someone in the community will propose 
something that doesn't introduce an agent dependency in the OS.
