Good news. VMware has released the beta of VMware Workstation 6.0 which supports displaying virtual machines on multiple monitors and running virtual machines in a headless mode (in the background without the full blown display yet still accessible by remote desktop). An even more interesting new features is the integrated Virtual Debugger which allows you to deploy and test your code from Visual Studio straight to a target virtual machine. Another wonderful addition is the ability to set a VM to be a VNC server so you can remote control them without having to install your preferred flavor of VNC. You can read more about the new features in the release notes.
