bearing in mind that most of these questions are applicable in
an infrastructure type application.  unless people want to build out a
tunneling infrastructure (which will chew up their b/w anyway) these
questions are largely moot.

there are a variety of mechanisms available to share b/w in this
manner.  captive portals with b/w limiting mechanisms are pretty
straightforward to configure.  applying intelligence at the edge to
address this is clearly the most scalable means of doing this. 

if this is a route that folks are interested in going we need to make
sure that there are "canned" configurations that simply require
filling in the blanks to get online. 

i can discuss a couple of sample architectures for doing this at our
next meeting if people are interested.  but given the geographic
difficulties associated with this type of network buildout i surmise
that this won't be a real issue for quite some time.

interesting thought given some of the recent activities taking place
with the other wireless groups around the country.

this is a nice segue into the issue of abuse.  while creation of a
public network is a great thing from a convenience perspective it is
also subject to abuse. people willing to share their b/w need to have
mechanisms to limit their exposure to this kind of abuse and mitigate
triggering flags on their SP monitoring mechanisms as well as staying
off the spam filter lists.

captive portals do provide a mechanism for circumventing some forms of
abuse.
