Push-based communication in NDN (and its security implications) was also
explored in the context of sensing and actuation. See these two papers:

J. Burke, P. Gasti, N. Nathan and G. Tsudik, Secure Sensing over Named 
Data Networking 
/13th International Symposium on Network Computing and Applications 
(NCA)/, Cambridge, MA, 2014.

Environments over Content-Centric Networking: the Case of Lighting 
<http://sprout.ics.uci.edu/projects/ndn/papers/ndn_lighting.pdf>, /the 
2nd IEEE International Workshop on Emerging Design Choices in 
Name-Oriented Networking (NOMEN)/, Italy, 2013.
