I don't know of anybody doing that, so no, no plans.

Yes.

Well, if properly done GStreamer and OpenMAX IL would communicate
properly and GStreamer would take care of the input synchronization.

The problems come with tunnelling and omx renderers, there are
proposals on how to solve the synch issues, but no one has implemented
them yet.

The best way to get involved is to ask questions here, or start coding
and ask for feedback :)
