of course the simple answer is one probably should not build such
sickness in the first place.  but if you insist on such a disease,
why should i pay for your being lazy and doing a half-assed job?

won't the mobile host either be
  o tunneled to 'inside' and hence will have the inside view of the
    dns
  o or living outside and hence have an outside view of the dns?

similarly to the designs it is trying to accommodate.  but, if you
insist on those kinds of designs, you need to do the full job.  don't
complain if insisting on kludge-A leads you to needing kludge-B.  "Oh,
what a tangled web we weave/when first we practice to deceive."

i doubt any of us like it.  but if you're gonna make a mess, it seems
your responsibility to contain it.  entropy and all that.
