Just a thought, but I would like to keep Koffice... I set my little brother up with my old laptop (800mhz PIII with broken hard drive) so he can do his work. OpenOffice takes 10 minutes to load, KWord about 30 seconds. Also, Gnumetric seems to be the only spreadsheet program that will actually make graphs and save them to proper formats (to be printed on my parent's Windows XP machine).
I seem to recall someone saying that both the German and English Knoppix versions have German and English OpenOffices. Why not take the English version of OpenOffice out of the German Knoppix CD and the German version out of the English CD?
Also: cut BB (in the 'Toys' menu), and TextXaoS (in "Graphics"). They're cool, but... If you absolutely have to have a Linux demo, there's always "Yellow Rose of Texas" by Fit & Bandwagon, Assembly 2003, and it's only 4 kilobytes, and uses SDL. Search Pouet.net. That would shave a few mb...
