I take mostly landscapes with my D800 and have been using both Live View and MUP (on a tripod and with remote release of course!) to minimise camera vibration.
My question is whether, by using Live View, MUP is irrelevant? As I understand it, when activating Live View the mirror is permanently raised up and remains up when the picture is taken. Hence there is no need to use MUP.
Have I missed something here or is my understanding correct?

Easy enough for you to test, next time you are in the field, with LV at max zoom and steady just thump the back of your camera with your finger and time how long it takes for the LV image to settle down.
I have only done limited testing of how long it takes for the mirror slap vibration to settle. I think for most situations, a 2-3 second setting is adequate.
The worst lens I have tested was the Tamron 200-500. It is very long - the barrel extends when fully zoomed and it has a long hood - and it is light weight. It also does not have a more rigid replacement collar or foot. I was testing it at 500mm against my Nikon 300 f/4 with a 1.7 teleconverter. Both were tested on a tripod with a cable release. The Nikon is a shorter and more compact lens with a replacement collar. Images were very sharp even with any image slap at fast shutter speeds. The Tamron 200-500 was very soft in comparison, but when I put a hand on the lens barrel and used proper long lens technique, the slap from the vibration was dampened and quality was near the Nikon. Shutter delay had a similar effect at 3 seconds.
I think Neil Rothschild has done some testing of long lenses for how long they take to fully settle. his posts are in the tripod forum. With long lenses, 4-5 seconds might be needed from mirror up to release. But proper technique is for a hand across the lens barrel to dampen vibration. With shorter lenses, 2-3 seconds is more than adequate.
Another option is to use the self-timer. I find that easier since it can be enabled right from the top of the camera. But I must admit - I have not tried it with Live View, only regular shooting, so I don't know if it would work with LV.
Either keep your eye to the eyepiece or close the eyepiece cover to shut out extraneous light.

The time required for vibrations induced by mirror-slap to dissipate will depend on a number of factors, including the mass (inertia) of the lens mounted on the body and the sturdiness of the tripod being used.
Bottom line - if it takes more than three seconds for vibrations from mirror-slap or manual shutter release to dissipate - then a stiffer tripod is probably required.
Many thanks James for another perspective on the shutter delay, although with my tripod and head... GITZO G2541 Mountaineer Series 2 6X Tripod Manfrotto 410 Junior Geared 3 Way Pan Tilt Head ... I am pretty confident that my set up is quite stiff but I'm always willing to entertain the possibility of being incorrect!
I think we have also established that in using Live View the mirror is permanently up and hence mirror-slap is a non issue.
There is a situation where you need a cable release rather than shutter delay. When shooting macro in the field it is often necessary to wait for subject motion to subside before releasing the shutter. When it does subside you need to release the shutter quickly before it moves again, as it always does. I agree that for landscape photography this would not usually be necessary.
