FYI, here's Rod Machado's info on this in the most recent copy of AOPA Flight Training:
Can a CFI log these landings?
Dear Rod:
We all know that as CFIs we can't log (for currency) the takeoffs and landings of our students. As a result, all of us end up getting in extra time to maintain our legal day and night currency.
Here's what I don't get. I fly as an instructor, five days a week, full time, and on average, I do three or four demo flights in a week, in addition to my regular students. Here's what confuses me: When I take a demo flight student up (brand new, never flown) the only hope the clients have of coming back to earth again is me. So, I am doing the takeoffs and landings even though they may have their hands on the controls. Why shouldn't the takeoffs and landings count toward my currency in this scenario?

Greetings Name Withheld:
The FAA partially responded to a question similar to yours that reads, "Certainly, an instructor could use a takeoff or landing for currency if it is being demonstrated and the instructor is the sole manipulator of the controls." This, of course, tells you nothing you didn't already know. So you have to use some common sense here to make sense of what's commonly not mentioned.
In the movie Transformers, Optimus Prime says to Megatron, "It looks like it's just you and me," to which bad boy Megatron replies, "No, it's just me." When you're with someone who doesn't know how to land an airplane, then, like Megatron, it's just you (and only you) who is responsible for getting that airplane down. It simply can't matter if another human hand happens to be on the controls, following you through the landing, while you skillfully land that airplane.
That's why the currency regulations say that you must make three takeoffs and three landings&as the sole manipulator of the flight controls. The dictionary definition of manipulate reads as follows: To operate or control by skilled use of the hands.
Since the FAA expects you to act logically in all matters aviation, it's hard to imagine how anyone, much less the FAA, could deny that you deserve to log a landing during a demo flight to a "non skilled" person who follows you through the landing on the other set of flight controls.
