Yeah - we have five 360 camera rigs that we're placing in five locations around a court for a basketball game, and we want the audio to go along with it. I've done audio with my soundfield mic for a single 360 rig before, and I've also used an "octa-aural" setup with 4 binaural mics - basically the same that was used for the Beck video.
Thanks for the suggestions! So far I've come up with nothing but I haven't exhausted all of my resources yet.
I have one - I'd be happy to rent it.
