Ah, so you're planning to use something other than IP since IP
doesn't work this way. My comments were based on Mobile Mesh which
uses both IP and standard routing.

Yes, this confirms that you are planning to use something other
than IP.

Yes, since you're not using IP or ethernet their limitations are
not your problem.
