Have you ever wanted to listen to music at work but you forgot the music at home on your computer.  If you have a Mac you can now stream your library from home or school or wherever you are on a network using HookUp.  You simply enable sharing on your host machine and setup a username and password.  You enter the the ip (provided by Hookup) and the username/password.  Your share then shows up on the computer you are listening from.  You could do this with 10 Macs all at once all in different locations.  You can also download files from the host pc if you wanted it on your own Mac.  When you have the chance, this is definitely worth a look.
