I can't make a statement on Microsoft's policy on implementing
P3P. I hope, that they will implement full P3P as the compact
policies have a bunch of disadvantages. 

If you serve your cookies from your site, than IE6 considers them
"third party cookies". "Third party cookies" without P3P compact
policies are blocked by any preference other than Low, if they
have no privacy policy. Be sure to send the compact header
already with the set-cookie. 

On the long run, you should think about an overall strategy of
privacy with your partners and include full P3P Policies into
this strategy...

Best, 

Rigo
