We both are :-) - but EVPN is nice for lots of the stuff where people
tried to made VPLS work at scale.  VXLAN is just another encapsulation,
but since that is fancy in the fast-but-cheap world, it's worth a look.

Yep.

(One could do that with EVPN/VXLAN based solutions, but I'm not sure 
this would be a really great idea.  Products are still a bit "young" wrt
to EVPN type 5 routes, aka "layer 3 VNI")
