mathijs, you might want to look into remoteStorage. It’s an open protocol for per-user data storage. As it also has identification & authorization, the log in is inherent. It’s kind of like OpenID + Storage, except that we don’t use OpenID (but rather Webfinger, OAuth, CORS and Get put delete on a key value store). For a developer, you just put in the remoteStorage.js client-side library and that enables everyone to log in to your app with their remoteStorage. Check it out at http://unhosted.org http://unhosted.org and http://www.w3.org/community/unhosted/wiki/RemoteStorage http://www.w3.org/community/unhosted/wiki/RemoteStorage There is also an IRC channel, #unhosted on freenode.
