Thanks for the reply - I am giving GRE a whirl with ESXi (GRE seems to be the choice for most). I haven't had much luck so far but it does seem counter-intuitive especially when dealing with traffic that does not have an IP header. It seems like L2TP might be a better option for connecting layer 2 spaces together.

I am using ODL Carbon for the controller and can get all OVS instances to appear in DLUX but I am missing the boat on interconnecting the switches themselves. So, VMs on the different hypervisors cannot communicate. The documentation suggests that patch interfaces can be used to handle this but it appears to be for bridge instances on the same OVS VM.

Yes, patch ports are just used to connect bridge instances on the same hypervisor.  You'll want to use tunnels to connect between hypervisors.  You should be able to find plenty of tutorials online.
