We're experimenting with building a data collection system that uses adversarial/multiplayer game mechanics incentivizes researchers to share (gain co-authorship) and excludes them from the benefits (e.g. co-authorship) if the minimum submitted data threshold isn't met.

Still early days, but we figured this is the only way to get people to share data, even within other people within the same project / lab. Similarly, I'm getting a lot of ideas from HN on event-driven data collection and immutable data storage to help make the data more tamper proof.
