I think it's going to take work from an integrator in all cases... How is it going to translate "developers free on Friday that know Javascript" into the three-way table join that you are asking for unless you first define "know" and "free" in terms of your database tables?
Apologies if I implied we just magically work things out, there is indeed an setup process where you help the app learn your ontology and how it maps to your physical infrastructure. This is, however, an iterative process, and you're likely to be able to get off the ground in hours, not days. Some people's data will be beyond us, I freely admit - in those cases you can do the work and supply us with something more or less resembling RDF.
I only object to what appeared to be magic. Now that I know there will be a setup it seems practical and useful. This is a great idea for exploring data, I hope you are wildly successful.
