Yes, exactly. So cloud is going in a different direction then DMM, unfortunately. > On the other hand if we just think mobility management entities as VMs, > spawning new functions here and there does not differentiate from what > we are already trying to figure out - from mobility protocols point of > view.

We need to develop a different set of goals for DMM implemented in VMs. What are the issues there? Certainly different than the issues we are considering now. Will control plane/data plane separation be the central issue? I am not saying we should not work on the current DMM direction. We can work on both.
