Thanks, SM, for finding what I said back in 2010. I still think this is architected wrong, conflating devices with communication endpoints higher up the stack, and steers us toward a path toward eventually "needing" to reduce privacy even more. However, 3GPP has apparently already already started marching down that path. Could our liaison explain the situation there? Is anyone actually going to use it? Is this a done deal - do we have to support it because otherwise 3 years of 3GPP work get undone? Scott
