Multiple ports per object would not imply multiple connections per object.
It would allow using one object to listen to 50 modem ports, 1 TCP port,
and one port for DECnet access, or for just one TCP port, without
rewriting it at all and never keeping more than one usused connection
object waiting for a call at a time.  Objects are cheap, yes, but why
not save them when it isn't a lot of trouble?

I'm not sure how a DB could 'move' into an online state.  'Be put',
maybe.  The important distinction is that when online the DB is
acting as an agent, and when offline it's a static document.  I'm
not sure if this is the real underlying theory of ColdMUD, but the
philosophy I extrapolated from the features that were in ColdMUD,
a philosophy I liked, was that it should be possible to do as much
as reasonable within the running DB, without shutting down the DB
or hacking the server.  I thought of an easier-to-edit DB textdump
as more a failsafe mechanism than a piece of philosophy, since the
more things you can do within the DB the more things you can do to
make it impossible to do anything at all, and by editing the DB
you can rescind these changes in an emergency without retreating
to an old checkpoint and losing all concurrent changes.  It's of
course perfectly possible Greg had other things in mind; I'm no
psychic.  This is just the way I've seen things since a couple of
weeks after I first laid eyes on ColdMUD.
