erkki,

i thought that dean meant with "dual registration" registering with two
different registrars (e.g. two srv records for the same domain).  in
that case, your problem does not occur if proxies are also paired with
the two registrars.

and third draft should be about connection re-use.  

if iesg or whoever still exists whose task is to keep rfcs sane, it
should definitely bounce outbound i-d back to the working group so that
it can do the right thing rather that rushing outbound that only
includes application specific solution to these generic problems.
