I figured: the media scanner can look in /extSDcard/Android/com.bt.sync/files/..., right? This will work, right? But it doesn't; if I put anything in /extSDcard/Music, it is picked up by DoubleTwist, etc, right away, but stuff in the part of the filesystem that the BT Sync App can write to is not found.
I looked for .nomedia files in the path, but didn't find any. The Linux guy in me wants to make a symlink from Music to the BT Sync dir, but that doesn't appear to be possible without rooting.
I use my phone for work and it is encrypted and has MobleIron, etc. on it; I think rooting is out of the question. Is there some way I can make this work?
