Yes, 1.5K spokes per hub is what I plan to end up with. I'm doing DMVPN phase III and using iBGP to send summaries. There's a little localpref and extended community stuff to set traffic flows. Just 3 routes from hub to spoke and one from spoke to hub (excepting larger spoke sites) and NHRP takes care of the rest.
