I'm curious -- are there any examples of what ping time would be from SF to NY if something specific like this existed? How much of current (additional) ping is due to queueing vs speed of light in copper? Or would this just make it more reliable -- instead of jumping around a bit, a consistent connection with reliable, predictable responses?
