Thanks for the reply, Regolith. What I'm thinking of doing is creating a graph that shows several different historical economic trends.
Rather than having a dozen squiggly lines on a single graph, I would create the graph in Flash, and have checkboxes so that the user could select which economic trend he would like displayed. The user could then either download the page, or do a screenshot, to use with an essay or term paper or whatever.
The reason I'd like to find universities that would be interested in such a tool is that I'm looking for link value for my site, and links from .edu sites carry more link value than from .com or .net sites.
Alternatively, I could find some of those sites that offer term papers and essays for students, and offer them the free use of my chart in exchange for the link value.
