There is a new Virtual Server white paper up at:

It is quite a nice write up on how to configure Virtual Server such that you have Virtual Server running on a dedicated computer - and then have the Web interface hosted on IIS running on a different computer.  This is especially useful if you have a large number of Virtual Server instances as it allows you to reduce the number of IIS installations you need significantly (say to 1).
