Will you eventually have to pay for usage of Google Maps (http://googlegeodevelopers.blogspot.com/2011/10/introduction...) if you go over 25000 views per day?
I'm asking because I'm cooking up a similar concept, and the upcoming price increase of Google Maps makes me a bit hesitant to use them.
The Google Maps Premier page, where my only option is to "Contact Sales" also doesn't seem very friendly to small sites and apps (http://www.google.com/enterprise/earthmaps/maps.html).
