Yesterday I went to El Segundo and talked to some of their guys about
what a community-wide wi-fi project might look like.
My strategy for stuff like this is always "do what works" (or, at least,
what I have seen work with large scale wifi projects), but I think that
there is some skepticism with working with cable companies and
providers, as they've been burned in the past. It will be interesting to
see what they finally do with Ubiquity stuff.
Anyway, after talking to them, I gave PacketFence another look for some
projects I'm working on, and I must say that I'm quite impressed on
where it's been going. Here are the install and admin guides.

On page 11 of the install guide, there are some VLAN examples that could
be helpful in various "open" campus environments. (Making a network
both "secure" and "open" is not easy). In the install guide, they've
even got some config examples for Catalyst switches and various other
routers, as well.
Those curious how ARP poisoning can be used for good (instead of evil,
as we see some motards use it for) might check out this Linux Journal
URL. In this case, it's called "ARP-based isolation" -- same pig, but
different lipstick.

(If any of you guys have any wi-fi security tools like this, let me know.)
