For all the effort of trying to get music to be sent from home to else where it would sound like an ipod or having a duplicate set of music at work is eaiser. I actually have a duplicate set of music at work since the rules for allowing various content through the firewall at work is changed on regualr basis when the Administration council decides that extra site or groups should be blocked or an updated firmware or software gets applied and changes the firewall settings unexpectedly.
The added bonus of having a duplicate set elsewhere is a perfect backup, especially when a lot of effort goes in to making sure that the tag info is just the way you want it.
