Howto failover and implement redundant Digimesh ??

Hi
I am trying to figure out how to add redundancy/failover to a Digimesh network.

My Digimesh network is configured with one module acting as a hub for many satellite modules. The hub is specifically named so after bootup, the satellite modules search for the named hub module. That works fine except that the hub is then a single point of failure. The hub and satellite modules are driven by micro-controllers, so functionality that is not included in the Digimesh protocol or the radio modules can be implemented in code.

Has anyone thought about how failover might be implemented??
