configuring XBees for multiple coordinator nodes

[williamcodes]

We're getting increasing pressure from organizers to put multiple sensors in buildings to avoid landlord retribution and to build a stronger case. Unfortunately, those organizers cannot deliver tenants either many floors apart (to avoid conflicts between multiple hubs) or very close together (to be close enough to reliably use one hub without dropping readings). Is it possible to configure the XBees so that two hubs can be used without interfering with one another or is that a hard limitation of the algorithm?
