     If you're designing all/most of the mudlib, maybe you could make some 
kind of replacement for this_user() that maybe uses thread-local storage 
(TLS) to store who the current user is. When a connection object receives 
some input, it sets a value in TLS to the connection's user-body (assuming 
this is a mud) before executing the command. Likewise, you could make a 
force_me(str) function in a user-body that does something like:

void force_me(string str)
{
     object previous_user;

     security checks;

     previous_user = this_user();
     set_this_user( this_object() );

     execute code for the command 'str';

     set_this_user( previous_user );
}

In any case, I hope this sparks some ideas that suit the lib you're working 
with. :)
