It (using port 80 for all sorts of stuff) is a pretty reasonable solution and many network applications do just this. If you want to stick to HTTP in order to overcome the smaters firewalls (are there such firewalls which are catually being used?) then maybe you can channel the IRC protocol over HTTP using a proxy. --Amos
