I had wondered whether that might be an acceptable solution for some folk. 
My original question was not OS-specific.  As you say, until chrony is 
available for a wider range of operating systems and supports GPS/PPS 
reference clocks it is but of academic interest.  As NTP already provides 
that infrastructure, enhancing the initial convergence rather than having 
to re-invent the whole wheel seems a better approach to me.

Happy Christmas all all our readers!
