I wonder what their terms on their "business class" services are.
Likewise, I wonder how much it costs to get T1 service without DSL or
the T1 SLA; If you've got a mesh routing around failure, you don't
exactly need to pay to call a tech out in the middle of the night to
fix a failure. (Which brings to mind another potential use for this
technology, actually...Enabling redundancy to reduce the costs
inherent in preventing individualized failure.)

I wouldn't call this a typical AP.  I have two of them, and I took one
of them with me to an anime con in Atlanta last September so that I
could use my hotel room's Internet connection without being stuck at
the tiny little table.  It worked splendidly for access from my bed,
and then I took my laptop for a walk.

I was shocked that I could still access my room's Internet connection
just fine from the lobby six floors down and through as many layers of
concrete.
