Forward: [Moderator Action] AW:Fw: Question on P3P

Sorry for addressing you wrongly with my concern. Recently, I read a note that
a harmonisation of CC/PP and P3P was done on protocol level. Apparently, CC/PP
needs something different than P3P to protect the CPI, as even the default HW
and SW profiles referenced by an URI in the very first http request might
contain privacy relevant information (e.g. type of device - if it is a very
expensive one). Another disadvantage of P3P are the extra HTTP round trips
which are very critical in a mobile environemt.

This seems more of a cc/pp question than an P3P question.
