thanks.  We aren't looking for performance extremes...  Would it be
reasonable to get an accuracy within several seconds, feeding sntp
clients on a lan from an sntp server which itself was fed from an NTP
server on the net?  Assuming a local clock which is nominally 60 ticks
per second?  And assuming the polls on both ends could be done often
enough to account for local clock drifts?

and thanks for the updated RFC...
