Winamp Remote, currently in beta, will enable remote access to your music collection on a PC from a PS3, Wii, or mobile phone. The best part is Winamp Remote will be free. Here is how it works in a nutshell:
The product is relatively simple; users store their music files on a PC with Winamp running. Then they enable the application for remote access. After setting that up, users fire up the Wii or PlayStation 3 web browser and head to http://winamp.com/remote to sign in. As long as the host PC is on, has Winamp running and connected to the Internet, the user can allow a friend to stream music and video from that machine too. If the user was on the road, at a party, over a friend's or trapped in a coffee house with bad music, they can access their tunes remotely from anywhere with an Internet connection.
(Note: Winamp Remote currently does not work with Xbox 360 because it requires a browser.)
