 * Is there any way to use W3TC as a “must use plugin” by putting it in the /mu-
   plugins folder? I know there are caveats with mu-plugins, specifically how they
   do not use Activation Hooks. I just want to know if there is a way to modify 
   the plugin so it will work on the multisite setup I am creating.

 * Following up here, I found this gist which has really helped get us most of the
   way there:

 * We are using nginx instead of apache, so the rewrite rule we needed was:
 * `rewrite ^/(?:[_0-9a-zA-Z-]+/)?wp-content/plugins/w3-total-cache/(.*) /wp-content/
   mu-plugins/plugins/w3-total-cache/$1 last;`
 * The final step that I’m stuck on is the w3tc plugin activation action is not 
   running for new sites, so the CDN queue table does not get created. I will post
   back once I have a solution for that.
