I'm working on the design of a system right now that is intended to be commercial if we can bootstrap it with profits. I had already decided to find an alternative to Google Maps because of the risk of getting technologically locked into a completely custom API/service. What, for example, would happen to our profits and bootstrapping plans if Google decided to, say, double or triple its pricing overnight? Big trouble right? So, here we have people who built around Google Maps wishing the prices were only tripled. I'm not yet sure what we will do, but we'll try to improvise something from less-featureful maps before we'll build a nest out on a Google branch and dare them to cut it off. I'm glad I learned my lesson from the experiences of others before this even happened. This is a great reminder about the hazards of designing around single-source, critical inputs.
