With Linux you can do the following:

Redirect all outgoing tcp connections to port 80 to a local http server with
the ipchains/iptables redirect target.

On the local web server you run a cgi which is opening (i.e. inserting an
normal accept without the redirect) into a rule chain if it receives the
"accept" button.

To remove the rule you can have a connection to dhcp or you simply flush
them every nite.
