Your router will have that information...most routers support a 
mechanism for retrieving your external IP address.  It would be nice to 
extend NetNameResolver to support a method like 
#getExternalIpAddress...you could support multiple 
ExternalIpAddresResolver's that use different mechanisms to fetch the ip 
address (i.e. hitting a web page, talking to a router, etc).  Something 
on a public webserver (perhaps operated by someone in the Squeak 
community) could be the last ditch place to get the external IP 
address.  Sounds like a fun little project.
