i have heard from various locations that it is possible to send sound output over the network and have it recieved by another computer? how do i do this... and how do i get it to work via the internet? will it work with a windows machine as the client?
basically i want to be able to control my mp3s on my home machine and listen to them on a machine in a computer lab at school (via headphones) or would the best way be just to burn an mp3 cd and cart that around (although i'd rather avoid that if possible), i have a 56k modem connection btw

p.s. the references i mentioned are rather obscure
