Excellent comment, thanks. We would require location and touch functionality. The core use case is really quite simple: users provide both text and numerical feedback based on their location - that's basically it. Nothing fancy. It needs to quick and easy to use, work on as many platforms as possible, and - given the nature of the application - is unlikely to be downloaded prior to when it's needed. People are more likely to use it "on impulse" and that's another reason we like the idea of accessing the service as you would a web site.
