One company I worked for had a mp3 directory all employees could mount
through nfs and listen to (don't know if there are legal issues to this).
On the other had my computer there spent most of its time compiling
(usually three or four heavy jobs in parallel) and four computers
connected to my hub usually soaking the bandwidth (network stress
testing mostly) so I ended up using a mini disk player since the songs
kept jumping and dying on me ;-)
