No worries. The only content changed was the [redacted] information. Since the zoom account is premium, they are static--and I didn't want to leave them on an open message board. Web scrapers are nasty things! There was no ill will in the editing of the message. 
Happy to hear you and Will were able to work things out!
It is somewhat possible to do what you're asking. We do not have high availability networks (2 simultaneous gateways talking to the cloud in one network) yet. However, it is possible add gateway devices as nodes. For instance, an Argon can be added to an existing mesh network, and it will act like a Xenon. It'll talk mesh, just not cloud.
High availability will come in time. The focus is to improve reliability of existing services. Some recent efforts have gone into cloud side reliability--especially in terms of sleepy devices. This has a significant positive impact on gateway connectivity for mesh.
Constant efforts are made to improve device reliability. At the time of this writing v1.2.1-rc.1 is our latest release. I encourage you to always update to the latest device OS and experiment.
