I was testing the UC capabilities of the Surface RT and loaded and logged into the Surface Skype app. I was greeted with a message “Merge Your Accounts” (skype and Live Messenger). After this one-click process…Skype to Microsoft Lync 2010/2013 seems to be enabled!
The federation is only IM and presence, but a great start. Below you see Skype for Surface RT running on the left and Lync 2010 running and receiving an IM on the left.

If you have any more tips using this new federation capability, please post comment.
