I was just browsing around wikipedia, and I came across this:
MKNAOMI was the code name for a joint Department of Defense/CIA research program lasting from the 1950s through the 1970s. Unclassified information about the MKNAOMI program and the related Special Operations Division is scarce. It is generally reported to be a successor to the MKDELTA project and to have focused on biological projects including biological warfare agents—specifically, to store materials that could either incapacitate or kill a test subject and to develop devices for the diffusion of such materials
So, MK is a designation for the department where this project was run. That leaves, for this biological weapons research, NAOMI.
Given Naomi's role in the MG fiction (medical support, creator of FOXDIE) do you think this is a coincidence, or an intentional connection? I just came across this, thought it was interesting.
