Well, during discussion with people about other MUDs someone tried to
convince me that a MUD (Mozart) could effectively install new code, areas or
whatever, whenever they wanted.  They'd do something called a fold or
that's what they called it, and although the game would go into acoma for
a couple of minutes, it would restart with everything as it was when they
paused it.. ie. objects on the ground where they were, etc etc etc.. and
it wasn't an actual reboot where people had to reconnect etc.
Needless to say I was sceptical, but this cool piece of information you've
turned up may well be the way they do it.. It might pay to speak with the
dudes at Mozart to check :)   ( 4500  (??))

Possibly worth looking in to, except for the almost certain portability
problems.  Obviously if you've got a "permanent" site it may be an idea,
but is anything ever permanent (oooh, how philosophical).
