It looks like Sun Microsystems is making good use of the work of all the volunteers who made OpenOffice.org run on OSX without X11 (i.e. in OSX speak: like a normal OSX application...)
The beta version is available, with the StarOffice logo instead of the OpenOffice.org one.
I have downloaded the beast but if everything is business as usual, we should not see much differences between the 2 suites, except for a few proprietary things added to the StarOffice version.

Also, NeoOffice is still running behind in term of code base but has recently released a patch for its 2.2.4 version:
