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.
