You need to know someone and you need to be packin' heat. I switched to 5.1 back in 2002 and started getting work just because I had 5.1 (and knew how to use it). Because surround delivery is a requirement for any distribution you might find, the lions' share of at-home indie dudes are assing themselves out automatically because they think stereo is adequate. It's not.
I'm 4 1029s away from going Atmos. I might have to. It's going to be the delivery format of the future and nobody knows how to author it.
