It's a bad idea for the boom operator not to monitor what he is recording. Now you've got a camera operator who needs to focus on camera and audio, and a boom operator who can't know for sure how he's doing. Recipe for disaster if you ask me. It's better to just plug the mic to an external recorder and just sync it later manually of by way of plural eyes or something. If you want freedom of movement with the boom you can still do that wirelessly and use a shorter XRL cable to make it less cumbersome. My two cents.
I do believe the guys at The Marmalade did it first, and better. http://vimeo.com/channels/343152/33408157
Tatoos and a beard doesn't make someone a "hipster", judging someone because they have tattoos and and beard does kinda make you a tiny bit of a prick though. The word "hipster" has been used so widely that it practically lost its meaning anyhow.
