I find that I still have to sudo to run pmc -u, even if I make the
server socket /var/run/ptp4l... permissions rw-rw-r--

Hi Jason, that's what the readonly UDS socket is for. With default
configuration and PTP4L master branch, this is how you can query
TIME_STATUS_NP without root:
pmc -u -s /var/run/ptp4lro -i /tmp/pmc.socket "GET TIME_STATUS_NP"
The key is to supply the "-s /var/run/ptp4lro" which points to the
read-only socket. You also need to pass "-i /tmp/pmc.socket" or
something similar - this points to the path where PMC should
create its own socket. By default, it is /var/run/pmc.$pid, but
that location is not writable for non-root users. So I just
usually point it to /tmp (this socket is practically useless).
