er, my mistake.
I have no need to use iTunes generated DAAP shares on my home network. My belief that DAAP did not support nested playlists was based on an apparently mistaken assumption. After a little testing, I find that iTunes generated shares do indeed include the publication of nested folders.
While I could make use of this functionality, I would rather see Ron concentrate on getting a few of the other database and playlist features on which he has been working implemented first.
