Doing a MVP is fine, but frankly your web-site is so light on details that I don't have a strong opinion about where this product would slot in.

I cannot help but immediately want to compare it to Ruby On Rails or Microsoft's MVC framework. They both offer a lot of the plumbing for you, and leave the actual content to you.

Maybe it is more akin to Microsoft Lightswitch, not sure.

But that might be just from my misunderstanding. It should be noted I watched the video without audio, and it just shows someone entering XML and showing a form.
