Thanks Dan and Chris!

Your links and examples, combined with the not-so-user-friendly IBM 
generator mentioned here (http://www.w3.org/P3P/details.html) helped me 
get these up on my server: http://chxo.com/w3c/

There are three files there: the xml privacy policy (privacy.xml) 
created by the generator, the "policy reference" file (p3p.xml) that I 
had to build by hand, and a file with Apache Directives that instruct 
the server to use a single w3c alias server-wide and to send a P3P 
header. Apache needs to be compiled with mod_headers enabled in order to 
do this. The P3P: header could also be generated by PHP, of course.

Hooray, it validates. Tested this on MSIE6 with a High Privacy Setting, 
and it took my cookie.

BTW in case you run into this down the line, you can View>Privacy 
Report... in Internet Explorer to get some idea of what's up P3P-wise, 
and there's also a Settings button in the same dialog box.

    chris.
