Wow, this really rocks. Funny to see this right now as I've been experimenting with web scraping for the real estate sector - a project that I've made available open source here:

https://github.com/RealEstateWebTools/property_web_scraper

One of the things I really would like to do would be to make a chrome extension to help people export data as they search for properties. Will look into this product as soon as I get the chance and provide some feedback.
