By folder watching, I mean: when I put a multimedia file in in a folder (which I've assigned to be 'watched'), iTunes updates the library. I'm very certain Windows has APIs for exactly this kind of situation. In fact, if they can do it for one folder, I'm having trouble seeing a reason why they wouldn't be able to do it for several folders.

You can do this with Applescript as a folder action. You can see how to do this here: http://dougscripts.com/itunes/itinfo/folderaction01.php

I was thinking that you meant live monitoring, i.e. your library would be a reflection of your directory structure with additional metadata stored in unit sections so that it scales better.

It's nice the Applescript exists (although I was talking more about Windows) but again, it's very sad one has to use an Applescript to accomplish this, on Mac.

I mean, a solution is out there: very good. Nevertheless, it doesn't justify or excuse iTunes for not having this feature.
