I've given this more thought.  Let us distinguish between NEA the
protocol and NEA the concepts.  The concepts are very well deployed,
mostly in the form of mobile device managers (MDNs), including the VPN
module I am using at this very moment.  These sorts of modules tend to
be two-sided vendor specific, meaning that little standardization is
required.  This works well when there are very few types of devices.  It
works less well when we don't even know how to count how many types of
devices there are.

I don't find that particularly satisfying, and I know my enterprise friends are even less enthralled.  They need a way to identify what is accessing their networks.
