It suffers from what is, in my opinion, a fatal flaw: it relies entirely on 
assertions that any PSO can publish with no external review.  Without some 
kind of third-party check on this, I don't believe there's any privacy 
mitigation at all.  

In previous examples, this has been analogized  to the Verisign sitefinder 
debacle.  Personally, I think it's worse.  Without an external check, this is 
a tool for enhancing the surveillance capacity of authoritarian regimes.  I 
don't find making the documents public so people can complain at all useful.  
The entities that will most want to use this will tend to be the ones that 
care least about complaints.

I'm not claiming an IANA registry is an essential part of the solution, I'm 
sure their are better ideas, it's just the one I thought of.  What we need is 
some location of information about domains that is neutrally managed in 
accordance with open processes.  That sounded like IANA to me, but I'm open to 
suggestions.
