Re: Comments on DMM Gap Analysis.

I am inclined to agree with Wes that DMM is hard enough already without
having clouds arising in the horizon. Cloud computing and such has a 
premise but I have hard time seeing how that would drive distributed
mobility management. I rather see it as opposite.. shifting the mindset
again towards centralized data centers.

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. The difference would be that the possible gateway is not a physical
box anymore. The herding of VMs is not what we are tasked to do.
