	That is just one of many uses of the DNS, albeit not one of it's best.

	Okay, so we're going to break the DNS because one particular 
mis-application causes security issues elsewhere, such as with new 
protocol standards like IPv6.

	Do we break the DNS every single time some whacko comes up with a 
bizarre idea to abuse the DNS in yet another way to inappropriately 
solve some other problem?!?


	Seems to me that we could instead require that IPv6 be fixed to 
require crypto-enabled authentication, instead of breaking the DNS.
