How do I create a sound input device in my System Preferences?

[Zectbumo]

Currently in my System Preferences -> Sound -> Input list I have these
two devices: Internal microphone and Line In. I would like to add a
new device to this list named "Sound Output". This device would enable
me to use the sound output as an input for recording when I have it
selected in the Sound preferences.

So far all I have found was this tech note page describing how to
create an AUHAL in C, http://developer.apple.com/technotes/tn2002/tn2091.html

What do I need to do to get a device to appear in the Sound Input
devices list?
How do I get an output device to feed into an input device?
Is there a way to do any of this using ObjC or (even better) using
Python?

Look into using Audio Hijack Pro for Rogue Amoeba, which does this for you.
