I don't follow this at all, but I encourage that you take this from 
the mailing list and put it into a reviewed, archived, and 
distributed document such as an RFC.

Are you saying that I could register "lurekiddies.example" with 
"www.childporn.com" as a name server, resulting in my issuing answers 
that have the address for www.childporn.com in the answer section? 
Or that it would convince COM to have the glue?

example's servers wouldn't have the glue for www.childporn.com, so 
hybrids wouldn't be sent, lame server answers would.

com wouldn't have that record unless there was a com delegation that 
claiming www.childporn.com as a server.  I assume (without knowledge) 
that COM no longer allows/carries glue in undelegated space (there 
was a time when).  I don't know about policies regarding using names 
in delegations.

I'm just writing trying to follow your point.
