110 right now, minus a few which currently are detected as unreachable or 
falseticker by the 5 monitoring servers in place.

Well, some continental and country subzones are in place (europe.pool.ntp.org, 
ch.pool.ntp.org), but not all (there's no africa.pool.ntp.org, no 
south-america.pool.ntp.org, and lots of countries are missing.

I'd like to insert the missing zones as aliases of a nearby, or of the global 
zone at soem time in the future to make autoconfiguration possible, but, 
well, you know how few hours a day has...

DNS lookup is only done at start up. The biggest problem right now is an NTP 
server disappearung - ntp clients won't try to find another one. Supporting 
DNS round robin server pools by upstream has been briefly discussed, but 
nobody stepped forward to implement it so far.
