One way to handle people building things where maps to is to invoke eminent domain: community projects displace deeded ones. This could be nothing more than a sweep that pre-checks the map files for deeded structures as part of the installation. Anything deeded that sits under a permenant object is shifted randomly via Object Displacement spell. There should also be some provision for thieves being able to break into the places. -- Steven Lembark 2930 W. Palmer Workhorse Computing Chicago, IL 60647 +1 800 762 1582
