With dynamic update the changes are smaller and easier to contain. 
Pretty much any change to a zone other than at it's apex (the domain 
name where the SOA is) or at some wild card (source of synthesis) is 
going to have a localized impact - for better or worse.

Is it good to spread name servers over different domains?  It depends 
on where the error lies.  I don't believe there's been a definitive 
study and I suspect that the answer would be that it doesn't matter 
much whether you do or not, no matter what the goals are.

As with IPv6, the problem with the deployment of frictionless surfaces is
that they're not getting traction.
