I have built a Subsonic Virtual Appliance:
http://dimingo.com/wixy/WixyBase-30.zip
This appliance is a vmware virtual machine, which has Subsonic 3.6 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.
Any feedback is welcome.
Best regards,
Giovanni
