It is not possible on Linux because upstream a) has no official support for shared libraries, and b) as Peter alludes to, upstream's unofficial choices for module linkage require a flat namespace. Linux certainly supports non-flat namespaces these days, but I don't feel like reading the linker docs again when it's going to require rocket surgery on every loadable module object file, or giving in and relinking instead.
