Novell is certainly not opposed to it. Not pushing it (as of now), but not opposed to it either.

The src.rpms are freely available for download, including for online updates, but not for a very few packages containing proprietary or at least not really opensource software (such as Java and a few fonts).

So.. except for Java (where updates could be backported from openSUSE I guess, it's just a package around Sun's binaries for versions below 7), there's nothing from stopping anyone who has enough time to do it ;)
