Wixy is a Subsonic Virtual Appliance:
This appliance is a VMware virtual machine, which has Subsonic already installed on a GNU/Linux (Ubuntu) operating system.
This means that you only need to download this virtual appliance and run it with VMware Player or another compatible player (VirtualBox, QEMU).
You don't need to install Subsonic at all. Just start the virtual machine.
An interesting usage of Wixy is to utilize it in the school language classes. The teachers can upload their lessons (audio/video files) to the server and the students can listen/see those lessons directly on their web browser in streaming.
