One of Us - Changelings and You

This is really cool, I love this idea. Maybe the mute button has some creepy flavour about the ghosts identity being absorbed into the ling.

That's a nice touch.

Regarding other comments, I think limiting the interaction to simply observation of and communication with the ling is the route to go. That way it takes nothing away from anyone's gameplay, only adds to.

While hearing all of the ghosts in shambling form would lead to funny situations, I immediately see this being used to metagame and grief.
