Instacalc Online Calculator is a neat online sharable application by Kalid Azad of BetterExplained.com (which has some nice explanations of things like Ruby on Rails). It gives you electric math paper, not cells the way a spreadsheet does. It evaluates in real time and handles all sorts of everyday things you need to calculate like currency conversion. You can share a calculation like the budget for a workshop by sending a link so others can create variant versions. While I’m not sure how I would use it, I like the simplicity of it. What would a text analysis enabled version look like? Here is a tinyURL sample link to a Instacalc sheet with what text handling I could find. Here is the embedded object. Go ahead and edit in it live!
