<p>So you want to add some persistence to your simple web app.</p>
</section>
<section>
<p>Okay so just require that each user have a couch installation.</p>
<p>Or make redis a dependency. Probably include some build scripts or something to make it easier since it's the only thing in the app that needs to be compiled.</p>
