For example, nowadays I'm participating in a team developing a intercom that has communication with smartphones. That intercom uses OpenSIPS, as a SIP Proxy, and must be connected to Internet all the time. I'm still not sure if such project can be considered in IoT context. By the way, that intercom is a thing connected to Internet.
Right now I think engineers have to see the term “Internet of things” as marketing stuff and focus on things that we can work on… :-)
The new challenges are with small devices that are very constrained and the IETF has been doing a lot of work in this area. Search for
COAP or 6lowpan and you’ll find some good discussions.

Right now all small boxes with connections to an Internet-based service is rebranded “IoT” - last week it was “Cloud Connected”.

The Internet Society hasa good introuduction to IoT you can use as a starting point
