How do you _automatically_ maintain a shadow-library? I always argued against the parallel-collection-approach as you'll likely run into inconsistencies while trying to maintain it manually.
I'm glad iTunes offers to transcode my lossless collection to lossy AAC on the fly before syncing to the iPhone (yes, some people still do that).
Of course my concern is storage in mobile devices. Yours seems to be flac support? However is that really an issue these days? I use ALAC (due to using iOS devices), but even then I never run into compatibility issues. Any worthwhile software/hardware supports either format - with Apple being the big outlier requiring ALAC.
