I’ve just tested v0.05 of this plugin using Songbird 1.0 RC3.
It works, and that’s it. You cannot filter or browse the contents of a DAAP share (yet), so it is useless for navigating a huge library.
Also the playlist order is messed up.
So give the dev some time to implement filtering and the whatnot, then this is usable, bringing a nice feature finally to Windows platforms also 🙂
