Hi SM, 

nice writeup. 

A few comments:

* You cite RFC 3365 with regard to what privacy means. RFC 3365 has a very 
limited view on that topic. 

* PII and personal data: In 
http://tools.ietf.org/html/draft-iab-privacy-considerations-03 we try to use 
the term "personal data" and define it as 

      'Any information relating to an identified
      individual or an individual who can be identified, directly or
      indirectly.'

We did that to avoid having refer to back to some laws where the interpretation 
changes from context to context and also over time. 

* Section 3 and 4: I guess that these two sections have the goal to point out 
that these identifiers may, depending on the context, allow individuals to be 
identified. 

* Section 5: The right amount of information

I believe what this section should say is that there are situations where one 
would like to provided information to the recipient so that a response can be 
provided and in other cases that's not desired. For example, in today's 
telephone system you can hide your phone number. Similarly, in SIP there are 
ways to prevent all information to reach the recipient. 

So, the question isn't really about all or nothing but it is about the ability 
for the user to decide about the context when they want to reveal information 
and when they don't. 

There is no doubt that it is difficult to decide about the right amount of 
information disclosure. But should this be the justification to always reveal 
everything?  

I agree that there is an asymmetry of power between the user and the entity 
offering services (which makes the situation worse).

Ciao
Hannes
