Thanks for the link to that article. I'll check it out. I'm the type of 
person that likes to fairly thoroughly understand something like this 
once I get involved in it. I've actually had NTP running as a client on 
my Ubuntu machines for over a year with a mostly default configuration. 
It was only when I got my hands on these "atomic" clocks that I started 
digging into it and customizing things. At the moment, I'm really happy 
with my Linux machines keeping synced to a few milliseconds of NIST. I 
don't think I'll worry with running an internal server on the LAN, 
unless I get some free time and money and just want to play with it.

Sincerely,

Ron
