Which raises my question of what PPPoE has to do with the solution and my point that PPP(oE) is widely misunderstood as other than a link layer protocol. Why use PPPoE to link networks instead of IP? > A completely new protocol could have been devised for all of this, > but since the nature of the info traded by that protocol would have > been very much like the nature of the info traded by PPPoE, I think > the authors wanted to use PPPoE precisely so they wouldn't be > completely reinventing the same old wheel.

So why not use the official IETF standard way to link networks instead of piling kludges on top of the kludge that is PPPoE? The IETF standard way would be to give the routers IP addresses and use a real routing protocol (or even static routes) instead of what looks sounds like a retread of IGRP. You might use PPPoE (or not) between the access concentrators and their neighboring stationary radios. You might define a PPP over RLP encapsulation that would have credits, battery condition, and so forth among the radios. Wouldn't that produce products with a wider potential market as well as fewer nastinesses such as an MTU that is even smaller than the bad old PPPoE MTU of 1492? Why egregiously violate layering by trying to convert IEEE 802.3 into an inter-network protocol?
