I might be a bit paranoid, but I'm a little hesitant to use a service like this when there's really no mention (yet) of the liberties I'd expect them to want to take with the data.
Wouldn't latency cancel out any advantage their faster algorithm might have?
Nice idea. Good luck.
Added the documentation of Place to my bookmarks, will review this this week-end.

Is it possible to restrict access to your own POI?
25 cents per 1000 calls? Is that a reasonable price? If you were to have an ad-supported page that requires a call to the DB then you would need to have 25 cents CPM just to break even.
