P3P and vCard-in-XML

Dear Frank, time ago I was asking for information on vCard, for the W3C's P3P 
activity. P3P is now coming back on the vCard issue, and I'd need to go on with
the dialogue. The main point here is that P3P has now gone to "last call" status, 
which is the final status before it can actually become a world standard.
As you can check from the specification http://www.w3.org/TR/P3P , section 4
defines a simple schema mechanism which has many common points to vCard. 
In the design phase, we tried to keep the basic P3P schema as much compatible to 
vCard as possible (in particular, the P3P basic schema should be a direct 
subset of vCard, when similar fields are defined).
Anyway, the vCard-in-XML draft now has the effect that eventually there will be
two different standards for the definition of personal fields in XML. 
Although both easily mappable one into the other (and in general, to vCard), this
makes us wonder if there is the possibility of a deeper integration (if it's
worth). That is to say, can P3P and vCard-in-XML arrive to smooth differences
as much as possible (in the ideal case, be one)? Or this is simply not possible, 
or too late due to timeline factors? How much room is there for such an aligning?
I'd appreciate your opinion on this important point.

To this extent, feedback from companies that are going to support vCard-in-XML 
is also important. I know of the Microsoft's effort with Office 2000 (that Lisa
Lippert forwarded to us time ago). Are you aware of any other efforts?

Thanks, and hear you soon,
-Massimo
