My Walkscore is 100%

Walkscore is an incredible website for learning what individual neighborhoods have to offer within walking distance.  Personally, living in Chicago, it is very important to me because my husband and I only have one car and he takes it to work everyday, leaving me to get places either by foot or bike.  But my home has a walkscore of 91 (out of 100), so it isn't a problem. 

This weekend I was at a cook out of some friends who recently had a child.  This live in a condo in the hip neighborhood of Roscoe Village(their condo has a walkscore of 90).  But now with child, you know where this conversation is headed, they decided its time to head to the burbs. 

My friend was telling me how she spends hours online looking at homes and school district information, which wasn't a surprise to me.  But I was surprised to hear her add "I walkscore every home I am interested in".  Hmmm.... this walkscore site is now becoming so popular is becoming a verb...

This got me thinking, what a cool service it would be if an real estate website was able to put a search field for walkscore in their advanced search capablities.  For examples, if you want to be pretty urban, show me homes with a walkscore of 80-100.  If you want to be more remote, show me homes with a walkscore of 0-20.  Walkscore does have some open source code posted on their site, I am not sure it is enough to create a search filter with yet.  If someone could figure this search out, could be a pretty cool reason to use your site verses another agent's in town.
