It already exists (Security warning: do not use it on strategic
machine, there is no warranty that these servers are trustful):

http://www.pool.ntp.org/

Active server count on 2006-04-12
Africa  1
Asia    24
Europe  368
North America   223
Oceania         26
South America   7
Global  582
All Pool Servers        653

The pool.ntp.org project is a big virtual cluster of timeservers striving to provide reliable easy to use NTP service 
for millions of clients without putting a strain on the big popular timeservers.

Adrian von Bidder created this project after a discussion about resource consumption on the big timeservers, with the 
idea that for everyday use a DNS round robin would be good enough, and would allow spreading the load over many 
servers. The disadvantage is, of course, that you may occasionally get a bad server and that you usually won't get the 
server closest to you. The workarounds for this is respectively to make sure you configure at least three servers in 
your ntp.conf and to use the country zones (for example 0.us.pool.ntp.org) rather than the global zone (for example 
0.pool.ntp.org). Read more on using the pool.

The pool is now enormously popular, being used by at least hundreds of thousands and maybe even millions of systems 
around the world.

The pool project is now being maintained by Ask Bjørn Hansen and a great group of contributors on the mailing lists.
