Hmm, would this work?

I've actually written some time ago an export operator that uses reflection
to "wrap" other export operators (
https://raw.github.com/dairin0d/export-selected/master/io_export_selected.py).
It's kinda hacky, but it does the job. I suppose a similar thing can be
done for the extension-based import?
