I am currently working on such a project. Search the list for Boost.Extension. You can send me any questions. I presented it at BoostCon.

It has been tested on Windows, Mac and multiple versions of Linux. It provides some basic object factory wrappers, but you can also use Boost.Function rather well. I'm also working on Boost.Reflection, which is designed to work with shared libraries.

There will be a number of additions to the interface over the next few weeks, primarily as a result of feedback from BoostCon.
