Dear Terry, Since the impetus for your question seems to come from algebraic topology, you might find two papers (each about forty years old!) of at least passing interest: "Coalgebras, Sheaves, and Cohomology": http://www.ams.org/journals/proc/1972-033-02/S0002-9939-1972-0294447-7/S0002..., and "Bicohomology Theory": http://www.ams.org/journals/tran/1973-183-00/S0002-9947-1973-0323873-8/S0002... With best regards, Don [For admin and other information see: http://www.mta.ca/~cat-dist/ ]
