SIX's idea was a bad idea.  Be a "master of your own domain" vs. including other domains.

As you know (and what kicked this off) is the fact that we requested (as we do) a specific reverse-DNS.  That's OK as we are requesting something within "he.net" and hence we should be able to add that to our own domain.  We added our own on SIX; but their dns is somewhat broken at the moment. :-(
