Very interesting question. With licenses which are only SLIGHTLY
assymetric (including CDDL and MPL) this is problematic - there is
no procedure to do this. There is no way (as far as I can see) that
(say) code issued under the MPL with A as ID can be merged with code
issued under the MPL with B as ID, because the MPL gives specific
rights to the ID that it doesn't give to developers (it is possible
it could work on a file by file basis).

With the OVPL it is easy. Either ID can (by using the sublicensability
under 3.3) decide that the other should be the ID, and sublicense the
entire codebase under the OVPL with that other as the ID. Equally,
and ID can take the whole thing GPL.
