Try using a chroot for it. If it is in a chroot jail, then the locking file it is creating in (/var/lock ? ) will be in the chroot jail. As long as it can find all it's libraries in the chroot jail, then the world is a happy place. With some caveats...

This is a long shot, but I'll mention it anyway: You might look into User Mode 
Linux (UML) which allows you to run multiple, separate instances of Linux on top 
of Linux, akin to VMWare.  If you did this on a server separate from your LTSP 
server, perhaps multiple users could start up separate Linux instances and each 
run CmapTools within.  I'd say there's a very good chance in won't work, but it 
would be fun to investigate.
