Your right, this hack makes sure your logged in before taking you to an antileeched link. I guess i should mention to those who can't read it that to activate it you need to use the ubbcode [al]download link here[/al] or [al=download link here]download wording here[/al], much like url/email but it'll return a ultimatebb.cgi?ubb=antileech;link=somerandomletters.
You can antileech anything if you want; websites, downloads, mp3's, doesn't matter. If you wanted to use it for your site, try making a new topic and put all your links in with [al], and copy the returned links to a page on your site. Just an idea.
I'm not sure about mp3 sreaming, it may or it may not work because i'm using window.open to open the links. I've never tried it before.
You can call the links from outside the board, yes. But if someone clicks them, they'll need to be logged in. Logging in should take them back to the download through referral.
Hope i answered your questions.
