That's how I designed my (wired) mesh, here though the mesh is used to enhance the reliability of datagram delivery in the presence of short-term overloads -- not as a necessary prequisite for packet routing. (i.e., any node *can* talk to any other node... but I don't want unconstrained traffic)

I spent much of my career facilitating projects in trouble. More often than not, the engineer didn't need help with a roadblock in his approach...he needed a new approach. When you hit a snag three levels deep in tunnel vision, sometimes you need to reexamine the whole thing from the top. Unfortunately, the guy at the top would rather blame the guys at the bottom instead of taking another look at his decisions. You can be forgiven for being late. Admitting you are wrong is not acceptable.> > tim > > > >
