If I encode stuff nowadays, I use AAC. Yeah, it's proprietary, but it's also a standard.
Also, the encoding format is not Ogg. It's Vorbis. Ogg is simply a wrapper (that's why you can get Ogg/Vorbis or Ogg/FLAC).
CompyFox, I don't really think the poster is trying to start a war of which format is better, but rather, trying to solve a problem that is a neat idea, but not really a problem, so to speak.
