There are two distinct tasks involved on the Mir side:
1. Forward cursor requests from Unity8 clients to USC (in general, from nested clients to host servers). Support for this was recently added to lp:mir (r2515).
2. Enable Unity8 handle input in relation to windows, grab handles etc. Although this should be doable with what released versions of Mir currently offer, the new window management interface should make it more straightforward.
The main blocker for this feature is (1), so I am going to marki this as 'fix commited' on the Mir side.
