Just thinking out loud here, but there's a big opportunity for the open source community within churches.
Many churches use Powerpoint and a data projecter to project song lyrics for the congregation. And those who don't already, want to. Small churches often have a desire to grow, but a very small budget. They dream big dreams but can't afford to buy them. Morally, they can't use pirated software, and $$wise, they can't afford WinXP, and MS Office. I'm not sticking my hand up, just having an idea, but if someone invited local churches to an installfest with the goal of getting a working "Powerpoint" machine operating for "free"...
