It seems impossible to create an addressing format that would include be compatable on all of the interconnected nets and would be parsable. Rob Pike, in a USENIX presentation, brought up the point about why would we want to have a single addressing format. Why not have a naming scheme for an individual net and "smart" gateways that perform the mapping between the nets. The different nets are radically different -- some centralized, some chaotic, some ... -- so expecting domaining (which is probably a good solution for ARPA net) to work on Usenet (which couldn't keep routing tables in >1000 sites together) is crazy. Besides, I don't think there exists a parser that could handle all the @'s, !'s, %'s, ^'s, and everything else that would work all the time. I think work should be done on creating gateways that can do the mapping between Usenet address and other net addresses rather than getting the whole of Usenet to convert or use strange and interesting address parsers and mappers. ..!{decvax,ucbvax}!sun!plx!adams -- Robert Adams
