Yeah, congrats and thanks for donating the code.
It is about time to replace that old java code. This swf already works very nice and looks significantly better / more stable and should be a perfect candidate.
A few suggestions:
a) A search function would be nice. So far is browse and playback only.
b) It cant playback anything but mp3 (just as the java applet which also cannot do wav or ogg).
c) The default DAAP server addy:port should be configurable in the html (I at least didnt see an option) and it should default to the sever:port that the FlashDAAP.html is on.
