The ability to publish music to the Tivo is very nice, but the fact that it only supports MP3 is very limiting. I like the convenience of being able to access all of my music via Tivo, but some music, especially classical, is noticeably degraded when converted to MP3. If a lossless audio format were supported (AAC-lossless, Flac, WAV, WM-Lossless) then I would be able to use the Tivo as my primary audio source. And I'm not talking about on-the-fly transcoding to MP3 as the "Universal Audio Plugin" does. I mean actually streaming lossless audio to the Tivo for optimal sound quality. This would make a Tivo much more useful to have, as it would take the place of a dedicated jukebox-type component such as Escient's Fireball, Sonos' product, or other hard-drive based players.
