Haha... Secondary purpose: keep my ears warm.

I've wanted to do something similar, but with a parabolic dish so I could get some directional feedback.

I had an ideal awhile ago. I wanted to integrate a pair of parabolic mics with a digital compass so you could mark bearing to a source of sound. Hook up the digital compass to a laptop which is integrated with a Rhino GPS so you could communicate both listener coordinates and bearing to sound to another similar setup.

It'd be pretty difficult to sneak up at night on two setups able to triangulate to brush noise. Heh heh, a battery of players with higher power AEGs could rain fire in when the sound source moves into range if you work out an elevation range table beforehand.
