It took a while to get around to it, but we finally got it posted.  You can download the MSI installer from http://www.microsoft.com/downloads/details.aspx?FamilyId=6A67F884-D629-4962-BD0A-C51BAD560354&displaylang=en.  For those of you who downloaded the source for the original BDD 2007 release, this source will install into a separate directory, and from there you can compare the two to see the changes made for the patch.
