Just an interesting article I found and wanted to save: http://www.thespacereview.com/article/1216/1.  It talks about the role of passion in the new Private Space Flight Market.  It also discusses the role of the Public Sector and the Private Sector, but like almost everyone else, it does not talk about the role the Non-Profit Sector could play to help make up for functions not being implemented by the Public Sector and that are too big for any one entity in the Private Sector to risk doing.
