[Skunkworks] Real Estate app

There was a story in the newspaper sometime in the last few days about a new Google Maps based app for real estate. I know this idea was shared a couple of years back on this list, and it seems like these guys who have built this are quite organized - they partner with other real estate companies, have extensive listings, its all mapped on Google etc. Unfortunately, the story did not carry a link to their site :) Did anyone come across this, and can share the site details ? Looked like an app worth seeing. R
