I may be presumptuous to assume that I'm a typical HP internal site admin, but I have a multi-hundred machine site that is adopting NTP, and want to offer a thought or two on the subject. We've put up a stratum 2 and several stratum 3's on our site, and have turned on a few diskless servers at stratum 4... we ran into some initial configuration and learning problems which have since been resolved, and expect to turn on all remaining standalones and diskless servers at stratum 4 "real soon now". But even then, the numbers will seem low since we run a *lot* of diskless nodes, and HP's diskless code already does good time synchronization between diskless nodes and their servers. So we'll only have the servers running NTP... therefore the number of machines "synchronized by NTP" will really be an order of magnitude larger than the number of machines "running NTP" given our average diskless cluster size. Not sure anyone cares, but it always helps to know what you're counting... Bdale, N3EUA
