> Who implements it ? That's an open question. Since Frank asked it, I suggest he could volunteer to do the work and coordinate the test and installation. While he's at it, he could also implement the automated service-area design that he liked so much (and convince the various LISTSERV owners that they should create a dummy account for EVERY listname in the network, so that you could send mail and files to any listname at any LISTSERV node without having to know where the list is held physically). This could be the start of something big, like a "Revised Revised LISTSERV", which could be written in a high-level language and run in all the known operating systems. It could also implement an X.500 directory (in addition of native X.400 support, of course). It is time for the elders to retire and leave way to the new generation... Eric
