Cool! Good stuff!

First thing: Do you need a *mesh* routing protocol? More specifically,
do you need a routing protocol designed for ad-hoc networks? I suspect
all your nodes are fixed, and will generally be seeing the same
neighbours for long stretches of time. That looks very much like a
fixed network to me. Granted, it's probably not going to look like a
typical LAN or WAN at first approximation, since you'll have clouds of
LAN, and hopefully overlap,  but once you layer a WDS environment over
the top, it starts to look pretty much like a bridged LAN between
nodes, and then either routing or bridging from the LAN clouds to the
intra-node LAN.

You want a routing protocol that will handle multiple default routes
(I assume that typically more than one node in a group has an uplink
to the big internet), and route traffic to the nearest uplink for some
definition of near.

I'd strongly recommend looking to OSPF or RIPv2 for your routing
protocol, unless you can clearly see a need for an ad-hoc routing
protocol. piertopier.net went for OSPF running under quagga on pebble
linux (for intel) and on openWRT (for the linksys WRT54G)

We've also beaten chilispot into submission. It's way better than
NoCatSplash, but you need a backend radius, and ideally an SQL
database so you can easily register/add users.

Maybe some of our docs might help:
http://wiki.piertopier.net/index.php/Technical

Or even have a look at the piertopier.net customisations to pebble and
openwrt as a starting point: http://www.piertopier.net/downloads.php

Good luck! If I can be of any assistance, give me a shout.
