Re: Increase bandwidth usage in partial-mesh network?

Hey! From the description it must be one of our clients!

Just beware if you go this route, a network that is probably already
unstable and unreliable will become at least an order of magnitude worse.
You can't fix ten lbs of stuff into a 4 lb stuff bag. The internet
protocols do not tolerate congestion well.
