I thought this article from Electronics Weekly was interesting; I never considered that we would need a new search engine for IoT devices, but it makes sense. What does everyone else think?
Interestingly there is a widely used search engine for IoT devices ( https://www.shodan.io/) but this is more a security researcher's tool. This was actually the mechanism they used for discovering vulnerable devices for the Mirai attack that took down Dyn.
I think what the researchers are more talking about is discoverability which is a topic that projects like Hypercat are tackling. Be interesting to see if we can really build this kind of ad-hoc M2M discovery and communication (car talks to a local traffic light) or if it will always go via a central API service as is more common currently (car subscribes to traffic service which serves data from a traffic light).
