Still under construction, but might become pretty useful one day: The "Swiss FOSS directory" by LOTS, the Open Systems Usergroup and UNISG.

I guess "FOSS" is bit of strange term. First of all it blurs the line between free and open-source software, and, even worse, sounds just like "fosse" / "fossé"[1]..
I guess "F/OSS" would be but slightly better, "libre software" is bad too.. Isn't it kind of a bad sign that nobody has yet found a striking name for that idea? Just cold and unpronounceable acronyms?

Well, studying both computer science and communication sociology doesn't help me to find something better, sorry.. but I keep on thinking. :)
