Allows you to create a feed for a view, much like Views RSS, except you can specify any custom markup you want (XML, JSON, whatever) instead of just RSS.
The MLS Module allows for Drupal sites to incorporate real estate listings provided by MLS services as CCK content. It opens the door for access to RETS and IDX based MLS feeds. Currently, you must also have VieleRETS installed in order to tap into RETS-compliant listings. For IDX based feeds, this module includes a simple API for turning csv-based feeds and their images into nodes.
There are a few major issues in the current codebase. I am slowly working to resolve the issues/put out patches/etc., but my workload continues to be very high which is preventing me from devoting much time to this project. I think all of the major pitfalls have been addressed in the issues for this project - please check them out to get an idea of what to expect and some of the necessary tweaks you might need to make.
