The first question that comes to mind is: how are you going to attach to the beam? It is a structural beam, I presume. Decorative beams don't count. Enough eye screws can work...but they can also fail. Is it big enough to do the job? Rather than eye screws, a better concept would be to attach a component that can be through bolted to the beam. Then the component can be removed as desired, the holes covered for later use.
