That is very cool. Any chance a company could run that tool on premises? I think there is a market for that.
Even if the manipulation were local, the Amazon API would be remote, and not within a company's control.
Interesting idea though. Most of the backend is portable perl and easy to pull out..
Selling that as a one-off utility would be hard, but it does currently work well as a hosted service via the webhook integration-layer, and a small amount of git-magic.
I will have a think to see if people would prefer it self-hosted, though nobody has expressed any interest in that previously.
