One of the major reasons I've been promoting the idea of the third party 
authorized list/DSD is to allow smaller domains that do not have the ability 
to do subdomain NS delegation to get the effective benefit of first party 
signing.  So, when I saw this:

I was interested.  Is a CNAME a reasonable alternative to the subdomain NS 
delegation approach that's been described previously?  I don't recall this 
being mentioned before.  It makes sense to me, but I certainly hadn't thought 
of it.  If this is viable, it changes, somewhat, my perspective on the 
significance of the requirement that we've stopped discussing for now.
