There are a couple of peeps in the forums that I know of that that integration is in the pipe line.

Several Real Estate add-ons are also in the works.

Keep in mind most are being developed for the Marketplace and it is time consuming as anyone that has worked on a Real Estate site can attest too.

I am sure someone will respond at some point with a possible time line of publication.

Thanks, that would be really great. The sooner the better I hope. I have a client that wants that and i would love to use C5 for the site, but need to start developing shortly.

Thanks,
Doug

i just submitted a real estate package that I've been working on to the marketplace (http://www.concrete5.org/marketplace/addons/real-estate/... ), but it doesn't access a IDX api. but it's my understanding that IDX MLS services all require a subscription and one master one for all areas doesn't exist due to the nature of the industry. here's some realtors discussing the subject:

I'll send you some info about the new real estate package in the meantime.
