Is this only available in select locations/cities, then? I'm not sure I'd terribly like a huge app downloading a world of information for monuments and things in cities/countries I'll never use.
It might be a good idea to look into post-install "city pack" downloads, where you can download some subset of data for cities you care about (or are about to travel to). Might be kind of neat also, and opens up a cognitive gate to letting people potentially just "browse" beacon information remotely in the cities they care about.
