Hi Alan,
I am just now setting up a storefront on Payhip where I will be offering the Ableton Live Set for $5 and the Excel listing for free. Prospective buyers of the Set are instructed to use the list to veryify that it matches their setup otherwise it will not work. I have not tested to see what happens when a playlist is created on the BB. I know this usually creates a folder above the folders list but I am not sure if this changes the folder number sequencing below the playlist. If it does this could be a problem for those who rely on playlists.
Finally it is always possible to use the Ableton Live Set to access a BB SD card that has been modified. This will however mean that the folder number references will need to be changed on any clips that have been displaced by the changes. That is fairly easy to do but it could be a lengthy process as there are close to 3,000 beats on that Complete Library Card.
