Definately.  A long time ago I had considered writing a chat server
that would auto-load classes that were emailed to a specific email
account.  The classes would be loaded as additional chat commands.
It wouldn't be too hard to do something similar with a MUD.  The
greatest problem would be security.

No need for a recompile or even a restart if you design it
correctly.  This is the reason for interfaces.  This is one of the
few features I wish C++ had, though you can get fairly close with
DLLs.
