VON/Microphone Commands?

[phronk 895]

I've checked the wiki and did a brief search on Google on how to control a player's microphone or VON volume settings via scripting commands, similar to fadeSound/fadeRadio/fadeSpeech, etc. but haven't found what will actually change the volume a player receives or transmits voice-over-net in multiplayer.

 

I'm assuming the command doesn't exist and would require some kind of intricate scripting or addon to actually work, but I'm hopefully I am wrong.  Anyone know methods on how to do this?

 

[EDIT]
At the moment, I'm using the enableChannel command locally, but I'd rather have the individual's voice lowered and still able to receive on same channel, if possible.

ALSO, is it possible to remoteExec or remoteExecCall a createVehicle command?  The question is related.
