Well draft-farinacci-lisp-crypto-01 with LISP-SEC can give you an authenticated DH mechanism as well.

Well I think we should monitor it but also not get distracted by it. 

The LISP WG has a control-plane that others may use. We should create laser focus on control-plane features and scale. The latter being most important.

There is broad support among other data center encapsulations as well. The point is being focused mostly on data center and not holistically.

The marketplace is confused about overlays right now in the data center. It is the vendors that are confusing matters by having (1) so many data-planes that can't interoperate in a multi-vendor network, and (2) coupled with separate and vertical control-planes that also don't interoperate with each other.

The risk is that operators may give up on overlays because the vendor community is all over the place. Or simply just roll their own with properitary SDN controller solutions.
