Uh, a good friend of mine did that a couple of years ago when he started a new design agency. He was going for a large government contract and they insisted on an in-house meeting as part of the pre-tender process. He had a large office space already, in preparation for growth, but only 1 employee at that stage, so he got his high school aged daughter in, as well as some of her friends to sit in the empty desks and pretend to work. A couple of the PC's at the back facing away from the meeting room weren't even plugged in, and were just screens on the desk and keyboards attached to nothing. It worked - he got the contract, and as a result, now has REAL employees at those stations, and in fact has to look at a bigger space to expand into.
