I've been traveling around the U.S. this summer doing speed checks and ease
of use and atmosphere at different WiFi locations.  I've been using Toastnet
and bandwidth.com to check speeds.  I believe they have a ton of data that
you might be able to use.

That leads to the suggestion of setting up a webpage that people could use
to help build their own maps and to help you create mega-maps.   You could
offer them simple speed tests or annotated maps.

Or some good homemade cookies like Mom used to make.  Seriously, look at how
well the SETI folks and others are doing on just having folks volunteer.  It
will work.
