https://www.hostsharing.net/That's a co-operative, non-profit hosting provider. It works kind of like car sharing: Everyone pays a monthly fee, based on the resources he/she uses, and that is used to fund hardware, colocation costs, domain registration etc. Administration is done by a team of volunteers, but totally transparent with discussions on mailing lists and phone conferences. A lot of the members are IT freelancers (mostly Java EE developers). Resellers are also welcome. Currently there are about 200 members.
Based in Germany, but open to anyone in Europe. The webpages are currently only available in German, but that doesn't mean that people who speak a different language aren't welcome. It's just that noone has found the time yet to translate everything.
