there are echoes lost in the valley

[jevolk]

there are echoes out to sea
as they undulate
some diverge and some coincide
but where ever they might be they won't abide

[tcpipuk]

Echoes swift, beneath ten millisecond's pace,
My pongs too, vanish without a trace.
In this dance of data, we're aligned,
Your fix, a beacon; my +1 signed.
