This just doesn't work.  It doesn't mean any thing to say  that a node is
in the juridiction  of a given LISTSERV. It means  something to say that,
at a  given time,  with a  given set  of node  tables, weight  tables and
backbone servers, a  node was in the "service area"  of a given LISTSERV.
But this may change the next minute  if new tables are installed. What do
you do  then? Forward the entries  to the new "service"  LISTSERV for the
node? But then, maybe this server still has the old tables and thinks the
entries should  be kept somewhere else.  So what will it  do? Discard the
new entries? Install them anyway? And what if a third server, which still
runs the old tables, sends a  "change" request to the first server, which
was but is no longer (although it might later become again) the "service"
LISTSERV for the specified node? You don't  have a can of worms here. You
have a full bin of them :-)
