IF you like the idea of Capture Pilot you'll like Air display.
It's an app and software to run on your Mac or PC.
It lets you setup a second monitor with touch screen ability.
You can setup lightroom with a two monitor setup
and use the second monitor as a display for your client or to bring close to the set.
Here is Air display:

Good for client viewing and sort of like capture pilot.
You can also use it cloning your main monitor and use it as a touch screen remote of sorts.
