It ain't a pretty site, but...
...has some great drapery track/room divider hardware solutions, geared to the trade, but he gladly takes single orders.
Mel Levin of Northport, Strong Island is your man. He's a character, and, at the moment, the only direct source I've found for some of the ceiling mount tracks and clean-lined architectural hardware (ADOglide system -- a cool example.) You can get your job done on his site and/or over the phone, and everything arrives quickly and cheaply. Plus, he's very good about being comprehensive in what he recommends and ships. MGR
