Far from a feature request, as Mark and fellow devs are significantly more intimately knowledgeable on the deep inner workings of transport, but I'm interested in understanding better on making routing between interfaces more granular.

For instance, a transport node with an Rnode that ties to 3 TCP interfaces to allow local Rnodes to communicate with the wider internet-based mesh, but not transport between the individual TCP interfaces. Is something like this easily doable? (bootstrap_only?)

Bootstrap_only is for interface discovery and means the node connects to that interface but once it discovers other interfaces it shuts that one down.

As far as I know you can't really set the internet ones to not transport packets between them. That would probably not be ideal for the network either.
