I would like to know this same thing. I know that OS X shows up in the "Local Services" in the Network browsers, but it would be nice to have zones. When I leave my zone, my computer no longer shows up under local. It is not accessible through the Network browser. Essentially, my computer is only on part of the network. Is this just an unimplemented feature of the OS X appletalk, or is it going to stay this way. One computer here with APpleshare IP under OS 9 only shows up in local services too. Is this because it is appletalk over TCP/IP?
