Just a quick heads up that we recently published our prescriptive guidance (aka recipe) for sequencing the Microsoft Office 2010 beta using Microsoft Application Virtualization 4.6.   Please note that:

This article describes one method that you can use to successfully sequence the Beta version of the 2010 Microsoft Office system for use with Microsoft Application Virtualization (App-V) 4.6. The method that is described in this article is not the only method that is available. You may have to change the information in the article as appropriate for your particular environment. 

This process should work on the final version of Office 2010 but of course until it's released we can't make any guarantees.  We'll update the article with any changes (if needed) once it ships.
