There are 2 great hosting services which offer free hosting for free software projects and are non-profit themselves:
TuxFamily for free software related projects. (I use them myself)
OurProject for free software, free culture and free knowledge.
By the way, awesome project! I can’t wait to try it out. Thus far I only knew about Lugdulo’V. (Do you also plan on using OpenStreetMap?)
speaking of hosting... have you looked at http://tuxfamily.org/en/about
About TuxFamily.org
> TuxFamily is a non-profit organization. It provides free services for projects and contents dealing with the free software philosophy (free as in free speech, not as in free beer). We accept any project released under a free license (GPL, BSD, CC-BY-SA, Art Libre...). > > Born in 1999 (oh! already?), TuxFamily tries to provide a good and reliable service to promote free projects, making them visible to the users. The hosting is free and we don't add banners or pop-ups to the hosted websites. You don't even have to advertise for TuxFamily! You can also use your own domain name if you have one. > > TuxFamily hosting facilities are running on VHFFS, which is a subproject of TuxFamily that makes it possible to manage a massive virtual hosting platform.
Services for hosted people
These are the services you can get with TuxFamily. Only one requirement: be a free (as in free speech) project.
Another 2 great free hosting services which are non-profit themselves. The requirement is that you intend to host a free project as well though.
For free software related projects: http://tuxfamily.org (I use them myself)
