Yes, clients can roam between meshes, but their IP address will change and existing connections will drop, as the roaming is not seamless. However, since this is between two buildings, this roaming will not happen frequently and maintaining two separate meshes looks like a feasible setup for...
Do you use the Reboot Scheduler? I have my Asus routers all set to reboot daily at 4:00 am. It's under Administration: System: Basic Config.
