Under iTunes 4.0, a lot of people started using music sharing to access the music on their home computers from work. Sadly, iTunes 4.0.1 removed this feature due to piracy concerns. Fortunately, you can re-enable iTunes sharing across subnets with the freeware Rendezvous Beacon.
After downloading and launching Rendezvous Beacon, create a new Beacon with the following values:
Now you'll be able to access the iTunes shared music on your home computer through your work computer's iTunes as if they were both on the same subnet.
Note 1: I feel that iTunes, because of its five-connection limit and the need to authorize computers to play purchased music, is a very weak platform for pirating music. This hint is intended simply for restoring a very useful feature that was removed by iTunes 4.0.1 because of Apple's fears of music pirating. Please don't ruin this for the rest of us by trying to iTunes for pirating.
Note 2: With Rendezvous Beacon you can use a similar process to publish services via Rendezvous that are served up by non Rendezvous enabled servers. This is potentially very useful for a net admin.
[robg adds: Unlike hints on defeating copy protected songs, which clearly violate the infamous DMCA, I don't believe there's anything inherently illegal about accessing your own music from another location. However, if I'm wrong, I guess this article (but hopefully not the site) will soon vanish in a puff of legal smoke.Mac OS X Hints
