That could be a steep requirement, since AFAIK vtable location and
layout isn't standardised, especially once you start getting into
multiple and virtual inheritance. And name mangling can get in the way
of finding the things to be called in the first place.
And memory management is always entertaining given that all sorts of
weird and different allocators can be in use even before you introduce a
different compiler into the mix. (Though this is where shared_ptr and
unique_ptr's pointer+deleter concept can get you out of a jam, although
it's more common to use opaque handles and explicit destroy functions.)
Having said that: if you can make it work, it would be awesome.
