We are working on an open source tool, WalkHub, that enables a community to collaborate wiki style on GuidedTours (or Walkthroughs, that's what we call them).

-Recording a tour could become a matter of clicking a record button; 
-Editing a tour, a matter of clicking the edit button in the tour and making a change.
-The tool automatically generates screenshots and an embeddable widget that you can use for example to show off new functionality on a blog

I heard about the GuidedTours project from Erik Möller at FOSDEM and I was wondering if the team that is working on it would be interested in our project.

This is a demo movie of our first recorder: https://www.youtube.com/watch?v=0ZWt4qfxU0U
