It would be cool to see a "Detailed" Tutorial from DNN Creative on using WebMatrix to build a DotNetNuke Module.

Like the documentation described here:

Any plans in the future? Is this a good idea? Thoughts?

It the webMatix vidio included how to install and configure web deploy on the server side it would be helpful.

Webmatrix is more of a deployment tool. You use it to install DotNetNuke on a computer. It will install all of the required dependencies like SQL Server Express and IIS, configure the website, etc.

If you are interested in a superb set of tutorials on building a DotNetNuke module, I recommend Chris Hammond's series in the Video Library at DotNetNuke.com about the Task Manager module.
