	Sure there is.  The primary thing I've seen people trying to use 
CNAMEs for is when they have an old name that they want to ensure 
still works, but they don't want to maintain all that separate data, 
so they want to alias it to the new domain name that they want to 

	Think also of the case where there is a merger or a buyout 
involving at least two companies, and only one of the names is being 
kept -- you don't want to just throw away all the old customers the 
day the merger/acquisition is complete, do you?  Surely a large part 
of what you're getting in a merger/acquisition is the established 
customer base, so why would you want to alienate them like that?
