I'm pretty disappointed in this entry.  It seems to dismiss the concept of a shadow government as part of somebody's nutcase conspiracy theory.  In fact, there are some real shadow governments at various places in the world.  The one I am most familiar with is well documented by Rosaleen Duffy, "Shadow players: ecotourism development, corruption and state politics in Belize" (_Third World Quarterly_:Vol 21, No 3, pp 549– 565, 2000)  I just spent over five years in Belize and the article is not idle speculation. 

 Altho I use Wikipedia frequently, I've never been a contributor, or I might volunteer.  I just think there's a flavor to this entry that I don't like much.
