Cyberspace as "physical domain"

My second post on this blog was on the addition of "cyberspace" in the Air Force's mission statement. Tonight I can across an interesting Air University essay, by 8th Air Force strategist David Fahrenkrug, on "Cyberspace Defined:"

The Department of Defense officially codified its understanding of cyberspace as a warfighting domain with the publication of the National Military Strategy for Cyberspace Operations. In this document, cyberspace is defined as a domain characterized by the use of electronics and the electromagnetic spectrum to store, modify, and exchange data via networked systems and associated physical infrastructures. According to this definition, cyberspace is a very real, physical domain that is comprised of electronics and networked systems that use electromagnetic energy. Cyberspace exists across the other domains of air, land, sea, and space and connects these physical domains with the cognitive processes that use the data that is stored, modified, or exchanged.

Perhaps if anyone is going to redefine cyberspace to better reflect its material qualities, and the challenges of its pervasive interconnection with the physical world, it's going to be the military?
