Hmm. I *think* that what you are proposing is more than just an "IANA  
action" or a model that fits into an RFC. I believe this would  
constitute far more reaching change than that. The change described  
above would also mean that IANA could declare a user of said IP  
address no longer the right user. That is quite a change from the  
model of today. That change might or might not be desirable but IMHO  
it's a different topic and will go into a large rathole that I think  
we will do best to avoid.

No, I tried to make a bad analogy.
