All of my music is my own -- I have the original CDs. My problem is that I very often move directories around, or tag the files on the empeg. These are then no longer spotted as duplicates, so I end up with two copies.

The correct solution? Not completely sure, but I suspect that it _is_ full automatic (2-way) synchronisation with the empeg or HSX-109. This would almost certainly require offline operation of emplode.

This also solves another problem I have: I keep my music collection in 3 places (2 different PCs and the empeg). When I move folders or rename files, using rsync means that I always end up with both copies reappearing on both ends. I can't use a single-master model, 'cos I rip CDs at both computers.

This problem applies equally well to my photo album -- I have a copy at work, a copy at home and a copy (abridged) on my website. Keeping all three in sync is something I've wanted for a while.

Now, the algorithms involved in doing this are fairly straight-forward. I just need more copious free time.
