We all know real estate is about location, location, location.

Did I mention location?

There’s a new set of location intelligence development tools available from Foursquare, which released their Pilgrim SDK this week (which they refer to as a contextual awareness engine).

More information can be found here.

Any developers investigated the SDK yet? What, if any, real estate uses can you think of? Notifying people of nearby open houses in urban areas?
