Summary: Tool for protecting AutoLISP programs exists.


     It can be done.  It has been done.  Autodesk has such a program,
called "The Kelvinator," available to authorized developers.  An
encryption facility for AutoLISP programs and menus is also available.
The protection provided by using both encryption and Kelvination 
is not airtight, but is probably comparable to that provided by shipping
executable rather than source programs.
