The freestore will be an app and media store similar to what is available on modern smartphones but for creative commons media and open source apps only. Initially released for electronic paper based e-readers as part of the fread operating system. At launch the plan is to only support fread apps and books, but to later expand into music and video and support other devices. Some old code from a first attempt is here but is mostly concerned with video, so won't even be relevant for the first version. I (the developer) am mainly focusing on fread right now, so freestore development probably won't see any serious progress until Q3 2016.
