OK, I have improved my article a bit: http://qumble.org/Downloads/Multimedia_Codecs_supported_by_various_portable_MP3_players_v2.1.odt
(also mentioned FLAC, Opus and Speex codecs, but I did not analyze market coverage for those) Plus added BSD license. Feel free to share this with others. -- -Alexey Eromenko "Technologov"
