One of the selling points for LRS is the idea of being able to collaborate on a shared touch whiteboard with others remotely. I recently tried an LRS out and found that the Lync software does not suport multi-touch. So you can only use 1 finger (or pen) at a time. The idea for improvement is for Lync LRS edition to support multi-touch whiteboards. This should also transpire over to Lync client on tablets and any multi-touch supported devices.
