Play music from PC on Android If I have shared a folder on my computer that has all my music in it, is it possible, when connected to the same Wifi network with my phone (Nexus One, Gingerbread), to play this music on my phone?

In case I need to use an application that mounts the shared folder on my phone, it would be extra awesome if it would mount automatically when connecting to that network.
One option would be something like the VLC app. You actually don't even need the music to be on a shared drive for that one to work, you just need VLC installed on the PC and a wifi LAN to share (or 3G and some network security know-how).

There are also some third-party apps that are designed specifically for the streaming aspect of VLC, without the local playback features, such as VLC Streamer.
