See slide 30 on this Neo900 presentation: http://neo900.org/stuff/ohsw2014/ohsw2014.pdf

Also see the various kill switches on the block diagram (GPS kill, modem monitor, mic not directly attached to modem (so you could probably send fake audio/silence),etc: http://neo900.org/stuff/block-diagrams/neo900/neo900.html

See slides 16 through 23 here for some details on the modem/audio monitoring/separation: http://neo900.org/stuff/cccamp15/ccc2015talk/talk.pdf

Would this meet some of your criteria? If there is something missing you can discuss with the people involved (on IRC usually): http://neo900.org/contact

It meets some of my criteria. They're doing good work. Gotta ditch that TI processor when possible. Need some hardware and software modifications. However, actual switches for power and audio coming through Linux part are positives. Removes some low-hanging fruit.
