Just an FYI in case you missed it but last Friday we updated some of the information surrounding 964051 with more on what we know about it as well as some of the workarounds. 

The updated official release notes are here: http://www.microsoft.com/technet/security/advisory/961051.mspx.

The clarifications on the multiple workarounds that are available were posted to the Security Vulnerability Research and Defense blog here: http://blogs.technet.com/swi/archive/2008/12/12/Clarification-on-the-various-workarounds-from-the-recent-IE-advisory.aspx
