Hi - can I jump in on this I'm looking for someone to help me with a real estate portal job and wondered if this was man enough for the job...has anyone successfully built an estate agents portal with this?

By using the "Dynamic Iframe" add-on I was able to display Open-Realty listings on my Concrete5 website. I did this by installing Concrete5 on root directory and Open-Realty on a subdirectory. Then I pointed to the url that I wanted to display within the dynamic iframe and that was it. Really easy to do.

I have a page mapper addon in the works that might be great for a realtor's listings. You put pages on a google map, drag the icon directly over the house(instead of potentially in the street or a few houses down, etc)

Merge that with a gallery block and a few others(or tony's real estate addon) and you have a great start to a realtor site.

I'd be more inclined to create something likehttp://hawaiilife.com in concrete5, i think that would be a fun job to take on.
