I think this is spot on.

In particular:  Patrick, for some domains at least, can implement a  
wildcard with the full cooperation and agreement of all of the  
customers of sub-zones within his domain.  Particularly if he doesn't  
resell any subdomains within it.  Verisign cannot. [1]

[1]  As a customer of .com, my own disagreement on this is sufficient  
to prove that they don't have unanimous agreement. :-)
