For Theora. They haven't really said much about Vorbis AFAIK. And I think an
audio codec is less likely to have patent issues than a video codec (especially
since Vorbis has a lot of high profile use that should have drawn out any patent
trolls) , and that is what Apple supposedly is worried about.

<shug> MS isn't quite who they used to be. They open-source things, and put
things under the open specification promise, and they seem to be very serious
about CSS3 and (X)HTML5 standards now. I think there is at least a chance of
them supporting Vorbis.
