Running WordPress with no database

Question

I was looking for a way to configure WordPress to run using only a filesystem database.

Sort of like H2 in Java, or in memory. Anyone?

Just for demonstration purposes

Answer 1

Not possible, one of the requirements for Wordpress is MySQL: http://wordpress.org/about/requirements/

If you just need a site for demos, you can run a local instance of MySQL pretty easily using XAMPP on Windows (and technically Mac too), but I prefer MAMP for Mac.
