I apologize if my previous messages have not adequately and strongly 
emphasized the issue: No cigar unless some way is found to either 
guarantee a priori that servers returned by a ad hoc discorvery agent 
have volunteered ubiquitous access (pool.ntp.org) or to respect the 
rules of engagement prescribed in the public lists. Routine violation of 
these rules has led to the premature departure of several servers 
operated by national laboratories, which is a damn shame.

If somebody independently discovers one of our heavily restricted 
servers and then comes up without knowing about or agreeing to the rules 
of engagement in the public lists, I get really ugly, inspirationally 
rude and in general creatively revengeful. There are a couple of server 
operators in the public lists who are even more inflamable than me.

Please note really very carefully, there are numerous private stratum 1 
and 2 servers whose access controls forbid no access outside the 
institution at all. We have many servers in that category now protected 
by draconian access control lists. You find one of those and you get a 
kiss-o'-death packet in reply. It would then seem to require ad hoc 
address collectors to properly respond to kiss packets.

Twiki not spoken here. Please keep this discussion on public airwaves 
and not in in chat rooms.
