Ok... Yet IMHO seems to be a problem better handled in the proxy layer. I
instead, and redirect the browsers that do not have the right cookie to
your help portal. The cookie may be a hash of the username, password and a
secret only known to you, so no section database must be kept. The
"Netscape Cookies" and "Basic Authentication" are similar enough, and I
think you can achieve this changing few lines of Squid code.
The only issue is that the browser will refuse to give a cookie to other
domain than that it was created for, so some creative URL redirection is
needed, like http://squid.auth/?url=http://www.original.url.com/. Anything
diferent from ^http://squid.auth/.+ will be redirected to an address like
above and if the user does not have the right cookie he will be redirected
to your portal, else he will receive the correct object. Just an idea, may
be I'm missing something.

As for the basic assumptions about individuality and self, this is the core
of what I like about cyberpunk. And it's the core of what I like about certain
pre-gibson neophile techie SF writers that certain folks here like to put
down. Not everyone makes the same assumptions. I haven't lost my mind... it's
backed up on tape.
