It was Ryan and not I who wrote about mode-6 - I protest my innocence!

I continue to recommend the reference implementation for Windows use, and 
I am grateful to those who continue to make a compiled version available.

It would be good to see even a limited SNMP capability included in NTP - 
for monitoring only, not for control.  Offset alone would be enough for 
me, although the ability to reproduce the ntpq -p display would be great.
