Actually any perl weenie worth $15.00 hour should be able to codify a fully
automated solution to this problem in less than 8 hours.
cvsup-master.freebsd.org already has the data on what servers are actively
updating from the master via the cvsupd.log file. Infact it knows exactly
what collection was updated on what server at what time.
Prune that data to a list of ``active and reasonably up to date servers''
and send dynamic DNS updates... viola automagic system. Hell we had a perl
hacker around here that made ${User}.portmaster.isp.com track who had what
IP address assigned when they logged in via dynamic DNS.
Now before someone goes off and tries to do this there are other harder
technical reasons that this is a bad idea, the major one being locality
of reference, ie we really don't want folks is Australia cvsuping from
servers in Russia now do we!!!
