My first job was at a place with a direct ARIN allocation and BGP to
Sprint and AT&T. I'm still friends with the remaining ops person and can
probably setup a peering session with him. I also have another buddy
with the ability to do BGP via Cogent.

Good question. Perhaps I could peer with my above mentioned sources and
http://www.quagga.net/route-server.php or http://www.routeviews.org/
(config instructions at http://www.routeviews.org/config.html)
That would be a fairly diverse set of views and hopefully sufficient for
my needs.
By the way I have a wiki page up with the details (more or less what I
outlined already) at http://www.socalwifi.net/index.php/Mesh_Experiment
I will write everything up there as well as post back results here.
