Code review comment for lp:~robert-ancell/unity-control-center/screen-sharing

Currently the system settings does not show any desktop sharing options [1]. Instead, you need to run the settings application [2] from the dash [3].

The proposal is to add a new panel to the system settings [4] [5]. If vino is no installed then this panel describes that [6].
