As cool as this is, it does seem to take the protocols-within-protocols trend to a farcical extreme. The stack for this is:<p>Upgraded Phone System (As opposed to POTS.)<p>Internet Protocol<p>TCP&#x2F;BSDSockets<p>WebSockets<p>WebAudio<p>A final layer so that you can emulate a POTS over WebAudio.<p>That&#x27;s not really any fault of the authors, I&#x27;m just curious how many layers we&#x27;re going to stack up before we start unwinding the coil for performance reasons.
