An article  just pointed me to the fact that the vision of the Internet of Things is about ten years old now, after early work has started at Auto-ID Center at MIT. This was my trigger to search for current papers describing and discussing the Internet of Things.
A rather critical articel, , proposes to envision the Internet of Things as a hierarchy of objects with different capabilities instead of a network of fully peer connected items, as layed out in the early days of the Auto-ID Center . In order to develop robust business cases, these heterogeneous requirements (tagging of strawberries, cheap items with short life-time, is different from cars with changing configurations) of objects have to be tackled with different technologies, e.g. barcode/RFID/sensor-networks. This is a reasonable argument against building an Internet of Things only RFID, RFID should be part of it, but others, barcode, as well.
Finally, I found a master thesis describing an art project about collecting and sharing stories about objects , which the authors calls an internet for things. It's probably not the killer-application but could be a nice consumer gadget for the EPCglobal architecture.
An interesting (but weired;) article is , where Rob Kranenburg (btw - the supervisor of ) argues for a society that should be in control of the (ubicomp) surveillance technologies it develops. The article is a little bit copious but provides nice arguments for why consumers should be empowered to play a mature role in an Internet of Things.
