Streaming media server

[Wendell Nichols]

I currently play my music (which is stored in a file system on a server 
on my home network) by mounting the filesystem via nfs and playing the 
files in amarok.  However if any disruption to the wireless network 
occurs, I lose the mount and, as you know, its hell to recover an nfs 
mount if the network has failed.   
What I'd like to have is something like a shoutcast server that would 
serve up my collection over a network connection or somesuch.  I 
installed icecast but it doesn't seem appropriate for playing disk based 
music collections.. meybe I'm wrong about that.
Any suggestions?
