I’ve been doing some work on Soundflower in the past week. This is my first foray into the world of Apple’s kernel extensions (kexts). There are a couple of things that are a bit finicky about them, but fortunately it is all very well documented. There is an excellent tutorial at http://developer.apple.com/documentation/Darwin/Conceptual/KEXTConcept/KEXTConceptIntro/KEXTIntro.html.>

It’s nice that Soundflower is getting a little attention now. It’s a really handy utility!
