Well, I finally got an alpha release out there of my script generator...  You can get a copy out on http://www.codeplex.com/nsot.  It is a C# WinForm app (vs2008) that can generate scripts for building a MOSS Farm or a single server install.  It includes all the options for installing and configuring an SSP, Excel Calculation Services, Indexing, as well as custom DB Names and specified ports.  Still haven't had time to do the "deployment" part I wanted to (which would automatically install as well as create the scripts)...  We'll see if it stays a feature in the future.

 Give it a shot, kick the tires, and see what you think...  This release is specific to MOSS, it will not work with WSS.
