If you're a Linux user and want to get in on all the Microsoft Zune magic—yeah right—here's a way how. The solution involves VMware and allows you to have a virtual machine running Windows inside your Linux, which then lets you run the Zune software to sync up your Zune.
The only catch is that you need to remove your USB 2.0 driver from Linux before you sync, which means you get to transfer all your songs at USB 1.1 speeds. Nice. This isn't optional—as of right now—and if you don't do this you'll get a nice BSOD in your VMWare window for your troubles. Happy Zunixing.
