A lot depends on how much “less than a microsecond” the chip sets really deliver in the real world. If they get down into
the sub 100 ns range (which they might), it’s a very useful thing for relaying GPS data from a roof antenna down to an 
NTP server in the basement. 1588 is a “less than a microsecond” sort of approach that does indeed get down to nanosecond
sort of levels. This could be similar.
