I'm using rhythmbox to provide a nice GUI to my parents; though I'm open 
to suggestions for other GUIs, the discussion here is GUI-independent. 
In jukebox mode (or even in album mode), it would be too much delay 
between playing songs.  I could modify the playing program to do:

 	system("cat file.flac > /dev/null &);

as it begins to play, but then if the user skips ahead to another song, 
it'll be catting a song no longer needed.  This could lead to scenarios 
where, if the user skips enough songs, I could be reading LOTS of files, 
so many my bandwidth is being swamped, all for songs the user skipped.

All I really want is a few extra hundred kilobytes of forward buffering. 
The AFS cache seems a fair place to have this done, so that's why I ask 
here.
