Imagine all the researchers you know, with a new bibliographic management tool that combined file storage with a napster-like communications protocol -- docster. Instead of just citations, docster also stores the files themselves and retains a connection between the citation metadata and each corresponding file. Somewhere in the ether is a docster server to which those researchers connect. They're reading one of their articles, and they find a new reference they want to pull up. What to do? Just query docster for it. Docster will figure out who else among those connected has a copy of that article, and if it's found, requests and saves a copy for our friendly researcher.
