Note that it is exactly collapse that
worries me most (having seen it first hand, in the most extreme possible
way, in the 802.11s mesh we used at OLPC). In that case, there was (maybe
still is) an N squared algorithmic issue in a "dense mesh", so scaling the
network up failed entirely at dismayingly few number of nodes.
