Although you can do it to a point with multiple virutal machine it still requires dedicated video cards and ports for the mouse and keyboard. It likely is not a cost effective to do that way. You are also very limited in the distance you can be from the pc. It is likely going to be much cheaper to just buy a bunch of low end machines and run one per user.
