I had a thought... would it be too difficult for Daemon to report the address the world is being hosted on when you open it? IE:
Sun Jan 1 00:00:00 2000
Welcome BYOND! (Dream Daemon release 337)
World hosted on byond://220.127.116.110:1234
A lot of hosts I know that have DSL or cable don't even know their own IPs, and those of us with dial-up aren't that sure of it either cause it changes everytime you connect to the ISP.
