A new Wikifact project could be a resource for real-time collaborative fact checking. It could serve as a fact-checking resource for the editors of Wikinews and Wikipedia articles. It could also serve as a fact-checking resource for a broader set of end-users. Through an API, end-users could perform real-time fact checking via Wikifact while authoring or reviewing documents.

I have created a project proposal here: https://meta.wikimedia.org/wiki/Wikifact . I hope to improve it as discussion unfolds.
