Seems to me we can do some process of elimination here. What people would like is a magic DNS hack so that you can tell your DNS server that a bunch of names are equivalent, and all the other software on the net treats those names just the same. Sorry, no pony. You can't have that. If it's an absolute requirement that no software outside the DNS can change, then our answer is clear: manual name bundling, with manual configuration of applications, we're done, so long. I don't hear much support for that. So what can we offer? If it's something like CLONE or BNAME, we offer an upgrade path. You're no worse off than you'd be with manual bundling and manual application configuration, and to the extent you upgrade your applications to know about the new DNS stuff, your configuration job gets easier. That's not as cool as the mythical magic hack. Will people find it useful? Having done my share of SMTP server hackery, I would. If it's as important to handle variant names as people say it is, they'll upgrade. If not, well, that's OK too. R's, John
