Whilst I haven't read/deciphered the entire lengthy proposal as yet, any
perceivable difference between blacklist programs and PICS facilitated
systems is becoming increasingly difficult to identify.

The PICSRules language: examples
Example 1: Forbid access to certain URLs
[...label example snipped...]
This example forbids access to a specific set of URLs, without using any
PICS labels. Any URL that specifies the host www.grody.com or
www.gross.net will be blocked, regardless of the username, port number, or
particular file path that is specified in the URL; any other URLs are
considered acceptable.
Example 2: Forbid access based on PICS labels
[...label example snipped...]
This rule checks the rating given to documents according to the "Cool"
rating service ("http://www.coolness.org/ratings/V1.html"). Labels will be
fetched from the label bureau "http://labelbureau.coolness.org/Ratings".
Labels embedded in the document are ignored because the document authors
can't be trusted to assess their own coolness. Documents which are not
sufficiently cool or have too many graphics will be blocked. Everything
else, including unlabeled documents, will be allowed.
[and on and on it goes]
