Given Vorbis plays even on old iPods > "hardware limitations" may not be a 100% accurate assessment. Note that "hardware limitations" isn't as simple as "can play". For example a portable player device uses 90% CPU to play things certainly work, but possibly for an unacceptable short time before battery runs out. / Jonas
