Winamp DAAP Client plugin = http://sourceforge.net/projects/mldaap
I also tried this a while ago. It is not really local only – one can use RendezvousProxy to have it access remote shares.
BUT, and its a big but, the thing does appear to be quite buggy and and in pre-alpha state.
It doesnt support passworded DAAP servers, it has bugs when the DAAP share changes after it read it and so on. Plus the version is from 2006. No development since then doesnt sound very active…
Would be nice if this plugin was as actively developed as fireflash. But as it is its not very recommendable yet.
