I always hated screen casts. I prefer creating a Word or PDF document with annotated screenshots which user can go through at their own pace. One of the idea in my idea list was to make it easy to take screenshots and annotate them and create a polished PDF.
But what you have created is even better. It is highly interactive and user can follow the steps as they work on the actual application. Extremely well done. I think you should market the hell out of this. I think there are lot of buyers out there for this kind of software.
What kind of pricing are we looking at?
P.S.: Always great to see a team of Indians creating a software product, I wish you all the best. I hope you also become as successful as Visual Website Optimizer guys.
