Please don't top post.

Maybe you could have both implementations available?  That way a user
could decide to do

struct point : BOOST_NON_DERIVABLE { /* whatever */ };

or

class Foo : public Bar, BOOST_NON_DERIVABLE_MI { /* whatever */ };

Not the prettiest, and the first example is not immune to subsequent
design changes, but that could be mentioned in the docs...

The best solution would obviously be a single one that works correctly
in all situations.  Good luck!
