The config I described (Frame, six amp cards, transformer rack, cobranet input device) is $6k in equipment with a good margin.
That's exactly what I meant.
The system could do anything that was mentioned in this thread, plus numerous other features that haven't been discussed. I'd sell this system without batting an eye.
No, you wouldn't, because that implies that this guy who is asking all sorts of strange questions, not listening to answers, and repeating himself, would never buy it.
Add a Crestron processor and touch panel for another $1,500, about $5k-6k in labor, and for $13k all of the problems magically disappear. Far from "cost no object".
$13,000 is in the realm of "cost no object" for 99.99% of the people who want this stuff.
That's not what you said. Or maybe not what the OP and myself interpreted your statement as. You said to run unbalanced line level over speaker cable, which is a bad idea.
No, I didn't, and repeatedly. I've added bold:

However, that 16-ga pair could easily take an audio signal that distance. The very worst you could do would be to get a small 70 volt amp, say a small TOA, connect the output of whatever is over there, and run its 70V output on that 16 ga wire to your volume control location. Match the voltage at the VC end so that you feed amplifiers there.

As I pointed out, that 16/2 can be used for a signal to go to the volume control location, which, because of poor design and a desire for a low bottom line, can no longer just be a volume control location.
That said "a signal." It did not say "a line level signal."

I cannot imagine the Cobranet would be considered, as I think it's a pretty expensive addition to the mix. Mike, what amount of money would need to be added to do what you're thinking of?
That's the comment you responded to.
I'd have much less than zero problem running audio on the 16 gauge wire. I'm telling you to run it as the output of a low-powered 70 volt amp. It's relatively low impedance, which itself immunizes it somewhat from induced noise. (Wrote inducted, meant induced)
Cubitus, you single out lack of shielding on an audio cable as a potential problem, but an audio balun does exactly that using CAT5. Shielding is not the necessity we used to think it was. Examine how a twisted cable rejects induced noise to understand this.
Giving an example is not saying "do this," and I didn't say line level here either, though it's reasonable to assume that's what would go on twisted pair.
The 16-2 is undoubtedly not twisted very much, so I'd be depending on the low source impedance to keep out interference.
...which would be the low source impedance of a 70 volt amplifier.
