Well, Rhythmbox’s DAAP implementation is buggy, anywho.
It doesnt suppotr browsing by artist, album, etc anywho, it can just list all songs.
Playlists seem fudged too, so I consider Rhythmbox’s DAAP support to be beta. Server-Side, that is.
Client-side seems more mature, but also staggeringly unstable, connection-wise.
I’d probably resort to a different player, if I had to rely on DAAP under *IX.
