I want to have my Empeg Mark II connected to my computer via ethernet so that other people on the network in my dorm can download music off of it whenever they want to. Right now they are connecting to it by typing in the IP address over the internet. Is there anyway that I can let them do this but not let give them access to changing my songs. Is there anyway to do this? Also what kind of damage can they do to my Empeg when they're connect to it this way?
