The Planck scale is the smallest size for any force or energy to exist in.
Actually no -- the planck scale is simply the smallest
observable scale. The reason has to do once again with black holes and the holographic principle. Say we accelerate a particle (in a particle accelerator) with so much energy that it would smash to bits on the Planck scale. Before that would happen, the energy of the particle would create a very small black hole. This black hole would simply get
bigger the more energy you put into it. So in other words, we can never observe anything smaller than the Planck scale, and even "at" the Planck scale is going to be several orders of magnitude over and above what we can do now. But there is a hard limit because of that.
It's a little like death -- no one knows what happens when you die because no one can see the other side and come back.
Interesting, but simmilary, you can argue that as black holes of this size evaporate very quickly so even if we can't measure anything at that scale because you would destroy the experiment, it is hard to imagine that anything can exist of a size smaller than the Planck scale and at a higher energy and still be considered to be in our universe as it would othervise evaporate. Quantum granularity also applies to the Higgs field as i understand it, so there might be a scale limit under which gravity, i.e. our universe, does'nt exist!
If Einstein still lived and had bothered with Quantum Mechanics, he would just have called it another veil of God.
But it is'nt a hinder to the Holographic Universe as less "bit resolution" on the event horizon is matched by less resolution in our 3D world.
One interesting point of a Holographic Universe is that the "real world" is on a surface, 2D+time, which actually makes string and M-theory a much better fit!
I started to write the following, because I was trying to speculate on your point. However as I wrote I remembered that the following is completely un related as the scale is completely wrong:
---------
I attended Holger Bech Nielsens last lecture as a tutor in October last year, and at the end of the lecture he entertained with one of his fringe theories:
Higgs bozons might exist in the wild and account for dark matter. They would be held in check by dark energy so they did'nt collapse back into the Higgs field. He said he had estimated these globuls size to be around 20-25mm. So his suggestion is that dark matter is generated if energies are high enough. If LHC started to make them, I would buy one to play with.

Rotational systems in fluid mechanics have some really weird entropy and thermodynamic behaviour, much of it to do with non-equilibrium effects and there is always the Mach principle to be aware of when describing boundaries for total system entropy .... Anyway, as I suspected this author seems to suggest some really strange artefacts inside Kerr geometry blackholes when using entropic gravity formulation.
