Again when Bill KU8H There is a very straightforward fix for this latency. Simply use a POTS telephone line with a phone patch. Receive audio comes in, and CW tones go out. At the remote site, a tone decoder generates key closures. I measured 50 ms latency on a 100 mile phone connection. And you never get audio glitches.
