A different strikefinder question

Seeing the thread on how strikefinders work was interesting to me
because my wife and
I had just been discussing strikefinders last week. We were doing the
Disney thing in Orlando
(buying our 9-year-old son's everlasting devotion), and we got to
wondering how far the
various strikes we were seeing each afternoon were from us. This led to
the question of
whether stikefinder equipment is even available for non-aviation
applications (ie either
car-mounted or portable); if so, what's a 'minimum-equipment'
configuration (portable GPS,
etc) that would put the information into an accessable and meaningful
form, and what would
it cost?
