Imagine if could remotely debug your app in a virtual machine running on your own box! Imagine if you could automate all this - building, copying binaries to a bunch of VMs, running tests against all VMs, copying results back to your system and shutting down the VMs. How cool would that be! Well, it is possible! In fact, some people are already doing all that, just not on the Mac. Let's hope Apple realizes the possibilities and changes their stance on virtualization soon.
