AFAIK it's actually not very difficult on most modern Unix platforms,
including Mac OS X.
The main technical issues are about how to handle module unloading,
which is greatly desired by developer-users, and rather scary to those
of us who have to support the product. AFAIK the main unsolved
problem is what to do about module-local Lisp data if the module gets
unloaded.
Anyway, Emacs has had dynamically loading support for several years,
it's just that the maintainers refused to apply the patch. I suppose
that the patches for 20.x probably can be updated for 21.x. Sorry, I
don't know where they are, and unfortunately Debian has apparently
removed its package versions, too.
