	Keep in mind that this is only a very crude load-balancing, and 
requires that round-robin be properly handled on the nameservers. 
Moreover, most caching resolvers *don't* do round-robin, so you are 
likely to still see a serious imbalance in the traffic load on these 
servers -- if one busy site gets the list of IPs with the 
least-powerful server at the top, then that's the server they're 
going to hammer and there's nothing at all that you can do about it.

	Using either of the other two solutions would at least let you 
get reasonably close to what you're looking for.
