Well, that depends, can you see the base floor joists? Do you have drywall ceiling or drop ceilings?
One way that you could do it, it would be ugly, but useful, is to place a 2x6 across at least 2 joists. Mounting them into the joists, THEN mounting the pole to the 2x6. THis should spread the load across 2 ft at least,
I don't know how LM can be mounted permanently, or if it can be done. From what I understand about LM is that it's very nature is not permanent, only the little plate thingy you push it in to.
The girl that does pole aria stayed with me while we were in vegas and we talked a lot about it. I saw it in person. It's pretty interesting, and will work beautifully on a permanent pole.
But there is a lot of torque at the top, so you need to make sure it's secure, checking it daily.
