The heat map integration is nice, I wonder why real-estate listing websites don't provide something like this already.
Maybe there is a business opportunity for you there (to integrate this with some of the websites themselves that you support).
Agree that there is an opportunity but less for me than for Route360. The integration is quite simple and I am sure their sales people already talk with some of them. So there is not really a need for me anywhere there. Only if pages want to include data from other websites. So on crib.ninja are you for example able to also add your favorite restaurants from Yelp, the sights of your city from Wikipedia, ... and display all of them at once.
