Semantics in the Web of Things

I often see writings by academics claiming that the semantic web model and its tools are ideally suited to solving the problems of the interoperability of things.

For example, here’s one such piece of writing on the topic:
"It is estimated that there will be around 25 billion devices connected to the Internet by 2015 and 50 billion by 2020. Such a stunning number of highly distributed heterogeneous devices will need to be interconnected and communicate in different scenarios anonymously. This implies that providing interoperability among "Things" on the IoT is one of the most fundamental requirements to support object addressing, tracking, and discovery as well as information representation, storage, and exchange. The suite of technologies developed in the Semantic Web, such as ontologies, semantic annotation, Linked Data, and semantic Web services can be uses as principle solutions for the purpose of realizing the IoT." -- Semantics for the Internet of Things: early progress and back to the future, Section 2<http://knoesis.org/library/download/IJSWIS_SemIoT.pdf>

While I see the point and tend to agree with it, I have to wonder how many of the really popular IoT products on the market actually have implemented any sort of semantic web technologies (ontologies, RDF data, an RDF triplestore, etc).

So, what products do you know of that have successfully implemented those tools in their things?
