OpsMgr 2007: Supported Clustering Configurations

I've been hearing a lot of questions lately about what the supported clustering configurations for OpsMgr 2007 are so I wanted to post this quick graphic that may help explain things a little bit.  One of our top Program Managers for System Center Operations Manager 2007, Satya Vel, put this together but I'm sure he won't mind if I share it.  I imagine there may be another scenario or two not listed here but hopefully this will cover the big ones.
