Hm, I don't quite follow...

   BOOST_CLASS_EXPORT(T)

just associates "T" with typename T.  Maybe one could cobble together
something like

   BOOST_ANY_EXPORT(U)

which would expand to something like

   BOOST_CLASS_EXPORT_GUID(boost::any::holder<U>, "boost_any_holder_" BOOST_PP_STRINGIZE(U))

But one of the OP's requirements was that a list of instantiations of
anys not be necessary.  Do we want to toss that requirement
in favor of moving closer to something that could actually go into the
library... or what am I missing?
