True p2p is the only approach that will work, not federation. I'd go futher and make the protocol high-friction for federation.
It's true that many p2p attempts have failed, but it's also the only solution that doesn't require someone running servers for free. There's evidence of success as well: napster (and bittorrent). Both were wildly successful, and ultimately died because of legal issues. It might work when the data is yours to share.
