Essentially you'd have two muds, a "real" one in which players  
move around, and a, much larger, "virtual" one in which everything,
including the people who are controlled by users in the "real" mud,
is just a statistic controlled by a simulated ecology (taking the
latter in the broadest possible sense; for the sake of argument, 
"there are always exactly 5000 wolves in the virtual world" is
considered to be a valid ecology).
Actually, I think that this could be a good way to simulate an economy,
though obviously one without emergent behaviours.  You can even solve
the spontaneous player creation problem: they are simply assumed to 
have entered from the virtual world, and the number of new players
created equals the number of people that moved out of the virtual world.

The question is, where are your crossover points from real to virtual,
and virtual to real?  If the virtual world is inaccessible to players,
it might as well not exist.  If it is accessible, the part that a 
player is in must -- at least temporarily -- be made real.  When the
player leaves, it could in theory be made virtual again, though the
player might be disappointed on revisiting the area that the dragon
killed has been turned into a statistic, and the dragon's head that
was mounted on a pole is no longer anywhere to be found.
Maybe a combination of real and virtual is best: no computer-generated
geopgraphy, physical changes to the virtual world are permanent, but
populations of living creatures are simulated until a player arrives,
and again simulated after the player's departure?
