Everyone is reposting the links for downloads to the new updates. The links for all of the updates can be found below….
Conferencing Add-in for Outlook http://office.microsoft.com/en-us/help/HA102368901033.aspx (now with a 32-bit and 64-bit option)
LiveMeeting Client http://office.microsoft.com/en-us/help/HA101733831033.aspx
Cumulative update installer is the way to go on the server side, and if you are using client version filter and device updater, I can report success (in conjunction with the link below) in our internal environment. So far nothing to report as far as bugs with the new updates, patch away!
I did want to point out a couple of blog posts coming out of these updates. One from Mike Stacy, which points out that with this newest communicator release you can now properly integrate with Outlook 2010 64bit. http://mikestacy.typepad.com/mike-stacys-blog/2010/01/january-2010-communicator-r2-update-compatible-with-office-2010-64-bit.html
Another being from Michael Sneeringer who is an OCS 2007 R2 MCM. With the newest update 64bit machines are requesting a 64bit version of communicator, or atleast a directory that has that specified. His post outlines resolving this issue, this has helped clear up a bunch of update issues internally. http://michaelsneeringer.blogspot.com/2010/01/client-version-filtering-on-windows-x64.html
