Well, how about a distributed directory service on Internet? It seems that it would be feasible to tinker with DNS a little bit to make it deal with area codes and place names rather than IP addresses and domain-style names. Eventually something like this will be required for the integrated digital network (as opposed to the Integrated Digital Network) anyway - that is, someday an ISDN connected subscriber will need to do PSTN-number to subscriber-name translation, and presumably anybody still using TCP/IP at that point will need to as well. Or has the CCITT already solved this problem for us? Followups to comp.protocols.misc. Jeff Carroll carroll@ssc-vax.boeing.com
