Based on iheartmemchache's post I read the paper too. I wasn't as excited about the project. There are similar things out there. One is Pyspread (which is referenced) that allows the functions to be written in Python (vs Basic). One of the engineers used this to do some pretty amazing analysis that would have well exceeded the capabilities. The issue with the paper is it tries to shoehorn in functional programing into the spreadsheet paradigm. Being able to break out is pretty important to make the user experience worthwhile. I also remember Improv, it was a great application and I used it a great deal. Borland did some extensions of their ideas in Quattro and I preferred their improved interface. All of this is a long way too get around to iheartmemchache's point, there is a lot of history out there and doing some more indepth research may get you to a better solution.
