I spent alot of time looking at this problem last year and came up
with a number of hack solutions (they are hacks because they rely
on undocumented, reverse-engineered information regarding shared
library and objective-C module formats).

I am told that version 2.0 of the OS will correctly support "real"
dynamic loading/linking.  I would suggest waiting for it; any other
hack is doomed to fail.

I might add parenthetically that NeXT official tech support was of
ZERO help while I was attempting this last year.  Of course I was
at a somewhat smaller company then. ;-)

My experience indicates that "knowing" somebody helps alot.  Or
flaming like a bandit.

If you are still interested in doing this, however, send me some
mail.  But you'll be sorry!
