This is, I admit, pretty cool. It's almost the dictionary definition of a massive abuse of technology, but pretty cool anyway. If they could make it work for telephone interviews, I might even get one.
Actually, as things stand now, I can't record telephone interviews at all. A few years ago, for no reason I've ever been able to figure out, my phone line suddenly developed a loud hum. You can't hear it during an ordinary conversation, though, only when you plug a tape recorder directly into the line or into the Mic jack on the phone. I've tried a million different combinations to try to figure out what's causing this, but no dice. The hum is always there, and it's loud enough to drown out actual conversation. Very annoying.
