Academics, I have a proposal/question and was curious if such a system would work for you. Here it goes:

Take a P2P program similar to Kazaa or BitTorrent to share paper pdfs and datasets.

Next to these files also share indexes, derived data for searching.

Next to that, also share user generated review comments and endorsements to implement peer review and quality filtering.

Finally, digitally sign all these data to guarantee provenance and credibility of the data found on the network.

Let me know what you think of it. I’ve been loosely working on a prototype application that does all that for a while.
