See "Our Attorney's Response To Microsoft" (posted by Roblimo) and this last article which brings up a very important point -- that Microsoft regards its contracts as trade secrets so even someone resourceful and tenacious would be unlikely to succeed in a FOIA request regarding the publicly-funded university's support contracts. Microsoft tried to censor information while crushing standards. Those institutions late in weaning themselves from Microsoft Windows can look at Samba 4 as an alternative.
