How is this done?

Hi everyone,

I hope this is the right place to post this.

I’m not the developer here, but I need to explain what I need to him. We have a client who has inquired about doing one of those silly viral marketing videos where the user fills in a form and sends out an faux email with a link for another to view a video with their name embedded throughout, similar to one of these: http://www.europeansportsnews.com/

I don’t need a code breakdown and such, but would anyone be able to summarize what’s going on in the Flash, as well as server-side, so I can ask the developer if he can do this? Thanks so much in advance!
