There are already regional pools.
What about multiple pools on the one line, such as:
pool uk.pool.ntp.org eu.pool.ntp.org
pool uk.pool.ntp.org eu.pool.ntp.org maxservers 7
where the default for maxservers is 5? I think that this type of client
configuration should be very simple, and not need multiple configuration
lines.
Cheers,
David
