True, that is one aspect. But another is that it allows you to have fids beyond the hard coded limits on the default player app. Once beyond that maximum, one of the first symptoms you see is that sync fails. You are able to upload the new files to the player, but the database rebuild will crash through emplode, and you have to rebuild the database manually.

I have not tried it with ethernet, so I am not sure the specific error number or if Doug is seeing this problem specifically, but the description seems very similar and the fid count (tracks + playlists) seems close enough to give the patch a try.
