The Instant SqueezeCenter 1.0 project as Virtual Appliance.
This VA takes the Instant SqueezeCenter idea to the next logical step, and allows you to run it on a virtual machine on your existing computer. You will need VMware Player, Workstation or Fusion to run this.
The approach here is to provide a 'raw' VM that you will customize at first boot. You set up all the user names and passwords. When you've completed the initialization, you have a complete virtual PC with a 25GB hard disk ready to accept your music collection.
