I am looking for a way to implement a download registration form using Contour.

So I was thinking about: - How can I use a workflow event to submit a file to the user using the HttpResponse? - Or how can I manually trigger a Contour form submit from within a surfacecontroller that sends the requested file to the user using the HttpResonse?

The form is not complex, it's just that we're already having some forms in Contour and our customer want's to reuse the Contour functionality to track incoming form submissions.
