Orca View Patch Functionality using C#

This post has NOT been accepted by the mailing list yet.
In Orca the user has the ability to open an MSI and under the transforms menu,
there is the ability to "View Patch" which appears to apply the patch differences to the Base MSI in memory, and it shows the differences by highlighting the changes in blue boxes.

I need to do this same thing programatically for a utility I am writing. I am trying to verify the contents of our msp files before they are actually applied to a system. Something like a build verification utility that verifies that the contents of the generated MSP file are what was intended.

Can we do that using Interop.WindowsInstaller.dll
