Invite some teachers and _discuss_ the use of free software
Good idea, but most teachers are (as far as I know) educated at a federal level. And usually support for school ICT projects (at least here in Belgium) is very dependent on corporate sponsoring. IMHO, we should try to lobby the countries and not influence the teachers, who represent the blind mass.
I don't know how it is in other countries but I don't think that someone can force the teachers to use windows. - If a school switches a computer lab to linux, so what? If they use linux instead of windows for wordprocessing or editing source, who cares?
As I said, I don't know how this is handled in other countries.
