A table of Windows equivalents.

Doug Loss posted this on the schoolforge list and I found it quite illuminating (maybe I need to get out more?) It is a table of equivalents / replacements / analogs of Windows software in Linux. http://linuxshop.ru/linuxbegin/win-lin-soft-en/ I was wondering if there was a similar list for specifically educational software? If not would it be a useful thing to compile? James
