I have Live installed on my laptop and share a mouse with my PC using Synergy. The PC is the host, laptop the client. It works fine for most things but I'm noticing weird things with using the mouse in Live (all versions of 6). It just doesn't handle right - dragging faders is jerky and hard to control smoothly and knobs jump from one end to another. I've now found that mouse zoom and double click zoom from the navigator are broken too. I've also reported this to the Synergy people:
