For the split audio the Prism 2 needs to be able to connect to wireless Bluetooth microphones, currently it will only connect to Sena Bluetooth headsets. Say you want to mont a prism 2 on the front of your motorcycle, the standard internal microphone is useless as there is to much wind noise, this is where wireless mini mics come into play just like DJI, Insta360 and GoPro all have. 
this would allow you to have one channel of the L/R audio be your mesh intercom conversation and then allow you to take a (Sena wireless Bluetooth Mini mic) and connect it to the other channel of audio and then secure it on the rear of the bike so that you can get exhaust noise without the wind noise overpowering it. 
Heck or even if you just wanted to vlog style with the camera it allows you to attach the mini mic to one or two people and have a conversation with good quality sound rather then the poor mic in the camera. 
please either make the device compatible with the likes of DJI mini mics or make your own Sena brand Mini Mic.
