I spent some time running tests and realized that using the discovery interface is a simple way of determining NSA availability for management of connectivity.  I was easily able to determine those NSA that were up or down.  Obviously, this capability would be useful in production implementations.

We could also add simple information to the hello such as NSA uptime or a last restart token to permit a peer to determine if perhaps an audit should be performed.  Pretty standard capabilities in production systems.
