If I understand things correctly, the fonts up at http://www.math.union.edu/~dpvc/jsMath/download/jsMath-fonts.html are based on the Bakoma fonts, and the license quoted above is the Bakoma fonts license. If you look at the "original Bakoma fonts" link at the jsMath fonts page, you'll see inside the zip file a file named BaKoMa-CM.Fonts, which contains the license agreement (and is quoted above). 1. Davide does not distribute this license agreement (or any other) with his modified versions of the Bakoma fonts. Does that mean he claims the copyright and he is the only one we need to work with for redistribution? 2. If the license agreement of the original Bakoma fonts is the one in effect, then it sounds like we might have to work with them as well as Davide to okay the redistribution of his modified fonts. According to the top of BaKoMa-CM.Fonts, the license holders are: ****************************************************************************** * * * BaKoMa Fonts Collection * * ======= Level B ======= * * Version 1.1/12-Nov-94 * * * * Copyright (C) 1994, Basil K.
