SIDE TANGENT:
On the subject of a solution being named the stupidest thing imaginable OR the exact solution:
I'm sick of using stethoscopes to troubleshoot stuff, so I've been searching for schematics for an electrically amplified one. A Stethaphone?
..They're called Contact Mics. $20 a pop.

STATUS UPDATE:
Apparently a volume knob you place in-line on an audio cable is called an "Attenuator".
I still assert that technology to sove a problem is named precisely what solves your problem, or the stupidest thing you've ever heard of.
In both cases, the person you ask thinks you're stupid.
