First I would verify if it really runs to microsecond accuracy, at least
when you require that.  My experience with small computers running NTP
synced to PPS that they have a tendency to be 1-3 magnitudes worse at
timing stability, probably because of the lack of a sufficiently fast
and accurate timing counter.

Of course, it could still be good enough when you want to use it as a
network time server.  It wasn't good enough for my co-channeling software
that requires the clock to be accurate within a few microseconds.
Intel CPU driven 64-bit PC systems have no problem with that.
