Hi Joe,

   It is avaliable in linux, and very easy to use. I posted in this list
   about using this type of interface (under Linux) to create dynamically
   loadable classes/objects (using the prototype pattern in Gamma's book).
   The subject was something like "Object databases..interpreters". 
   
   In any case, the  functions you want are called dlopen(), dlclose() and
   dlsym(). dlopen creates a handle for a shared library, dlsym gives you the
   address of specific a symbol..etc. See dlopen(3)....

   Read the other message I posted, it also talks about having a "registry" 
   that contains information about the available dynamic loadable objects.
