listen to the mad man
I personally vouch for this. I have AirPlay receivers in every room except my kitchen, and I use this to turn my MBA into a receiver so I can listen to music while I'm doing the dishes.
Spoken as somebody who has never started a gigabyte plus transfer of multiple files and then went to do other things.
Or in most common use case, copying multiple terabytes of 2+ million files and nested subdirectories across a network connection :/
