Ive said it a million times before: in research, if open data mandates mean that all data needs to exist on some cloud server, we are in for a catastrophe of the highest order where cloud providers will be in a position to siphon off however much public funding they want - the "free open data" programs are bait. The corollary is the continual rise and sudden collapse of archives who miss one grant cycle or cant keep up with the infinitely expanding cloud bills.
Its not just a disaster for private data, but public data and the whole of the web. If researchers want their disciplines to continue to exist, to contribute to a healthy information ecosystem, and to realize the promise of the web for science, they should be investing in and demanding p2p infrastructure.
