[arm-allstar] Theorhetical node limit

[Mike Sullivan]

All, I am working on designing systems to link up area repeaters and
working on different concepts. I plan on linking each club's system via
Allstar, then also have a radio backup/link to other area repeaters for
as-needed use. I was wondering if there was a theoretical limit to how many
interfaces you can have connected to a system. My goal is to have the
repeater as the main node, link them over Point-to-point links, and have
link radios for linking to other repeaters/systems acting as local nodes.
