Thanks.  It's off the ground.  I get a screen full of ntpq printout when 
pointed at a system with lots of servers but nothing ever appears on screen 
when pointed at a system with only a few servers.

Ahhh.  I didn't wait long enough.  I think it was off doing DNS lookups.  I 
have what seems like a reasonable example with a 30 second update cycle.  
It's got 5 IPv6 names that don't resolve and I have a download running on a 
slow DSL link.  All other names are local.

A system using the pool will have similar problems - all names will be 

I think it would help to flush each line.

A cache for DNS lookups (including fails) is probably a good idea.  Hammering 
on DNS is not polite.  Is there a python package that does that?


These are my opinions.  I hate spam.
