Just added two updates to the project details:

Nice Project! - Do I need this? - How will this project benefit the average 3d printer user?

I Love My Extruder! Do I have to use yours? - Explains that a compact design is an option that will fit in an existing bowden extruder system.

Processing sketch for graphing the force sensor outputs on a computer is ready to publish, just got to set-up Github for it. Should be useful for projects other than this.
