Maybe I'm misremembering RFC 1034, but a CNAME chain only violates a 
"should", and later in that RFC it says that software "should not" fail 
to handle chains, so even if you take a "should" as gospel, the "should 
not" should be equally gospel, making CNAME chains supported (although 
not advised.)
