Sadly, the hyperlink near the end for how to use a Startup Script for deployment doens't work.  The ability to deploy a highly customized installation with MSI/MST is gone with 2007 and I'm hoping startup script deployment may be the way out of the madness.

In our shop we'll be deploying new machines/images when we roll Vista later this year but we had hoped to deploy Office 2007 before that. However without a truly funcational GP deployment method we may have to wait.  

What was the Office team thinking when they blew up GP deployment?!!
