Hi Jeremy,

During the last weeks I've spend some hour on boost.extension.

Organizing factories is what boost.extension is all about at the
moment. But I think means for portable loading of DSO (Dynamic Shared
Objects) are worth a project on its own.  Consider this structure
  - boost.dso
    - portable dlopen
    - convenience classes for resource handling
  - boost.extension
    - factory pattern
    - reflection pattern

boost.dso will IMHO be suitable for many developers out there having
their own factories running, but like to have a well tested and
portable dlopen (aka. LoadLibrary on MS Windows).  Providing this
needs a heavy testing harness which will take a notable amount of
developer time.

boost.extension itself can concentrate on how to plug and organize
loaded code into an application.

What do you think?
