1 - The shared_library class provides for finding any function in a shared
library that is declared extern "C", and being able to call it. It can call
functions with various signatures just fine. If you need more than 6
parameters for a function, just redefine BOOST_EXTENSION_MAX_FUNCTOR_PARAMS
to the number of parameters that you need, and Boost.Preprocessor takes care
of the rest.

2 - I have nearly finished the mechanism for reflecting out arbitrary
functions (non-member functions) from a shared_library. This will make it
possible to overload function names, and require less 'extern "C"'
functions. It sounds like (1) will work for you in most cases, but if you
want to do anything more complex, (2) will be more appropriate.

3 - You can also use Boost.Reflection to create and call methods on
arbitrary classes. It works with shared_library. It does not require
inheritance.
