Custom IDX Solutions
Definition of a custom IDX solution: A custom IDX solution is technology provided by a vendor servicing an MLS board through the query of a raw data feed (Typically RETS or FTP) - what separates a true "custom" IDX solution from what are commonly referred to as "canned" solutions is that the customer of the vendor can have changes made to the IDX solution to fit their needs, whereas canned solutions are what they are, and do what they do - you typically cannot request anything past minor cosmethic changes.
