I'm sure some will find this library would be useful; I worked on a project that implemented the factory example in a Windows & Linux environment. Unfortunately, these types of systems are also brittle (ABI). Is there a way to add a symbol that acts similar to the soname automatically? If group A provides a boost::dll plugin with an explicit version, and then group B doesn't request that version when loading some symbol from the plugin, boost::dll automatically fails in all load functions. This way a provider of a plugin can force the user of a plugin to think about potential ABI problems through the boost::dll interface.

The use-case might be too narrow though, especially since the importer of boost::dll should really think about these issues. However, is it worth discussing ABI issues a little more in the documentation, or at least point to a good external resource (the Drepper paper)? Someone who finds this library may be less knowledgeable of such issues.
