Yes, aware of them. There's been another snapshot of the moblin beta since then. I'm using that, and the main repo here for references.
http://repo.moblin.org/moblin/development/core/source/
There's also some packages requirements in rawhide already (like the newer clutter) and some Fedora packages that need patches etc (like xulrunner) but I'm not quite sure how I'm going to deal with the later as yet.
