A semi-similar scheme was already used for adding multihomed hosts in
the VLDB, so I was assuming that a similar thing would be used for the
addresses in VLDB entries; you just make a different call instead of
GetAddrsU to get the actual addresses.

But that's only for the VLDB. For other places, it sounds easier to just
update the structures rather than create a whole new mapping service...
but I haven't really thought it through.
