8. V.A. Ilyin,, RIGF, 14 May 2010 Internet and Science 1993-1994 two revolutionary events: - NSF «presented» DNS to the «commodity» governance - WWW had come from the science kindergarten to the adult life During 90's-00's Internet has got many faces: - commercial - social - national - governmental - private -... Now science descryes (first of all) COMMERCIAL face of the Internet, with (afterwords) administrative actions at governmental levels

9. V.A. Ilyin,, RIGF, 14 May 2010 This consecusion: commercial face at first, and then governmental interventions in many cases (especially in developed countries)‏ means lack of corresponding Internet Governance solutions for Science life in Internet... science should not be as VIP subcommunity in Internet...... science is (and will be, for sure) at the Internet technological top, showing realities for future innovations in commodity life...... science shows no direct commercial interests, but can play an accelerator role for trading Internet services...... the problem looks as local/specific etc, but... No solutions on the surface...
