The current ntp-dev is actually closer than you might expect. The pool
command gets a bunch of servers via DNS. If one of them stops responding, it
will get kicked out and replaced by another server.
It's only SMOP to make it kick out the worst server every now and then. That
should converge to at least N-1 good servers. (If you have N good ones, it
will kick out the worse which might get replaced by a poor server. I suppose
you could tweak the selection to require something like more than x% worse
than the average or best or ... Simpler to ask for N+1 if you want N.)
These are my opinions. I hate spam.
