 * Paul, you might be interested in this post about [Installing a WordPress mu-plugin automatically](http://neliosoftware.com/installing-wordpress-mu-plugin-automatically/)
 * In the post, the author explains how they created a function allowing users to
   press a button to copy the “must-use” php file into the “/mu-plugins/” directory.
   Maybe your plugin should run some kind of code that would, on installation, move
   the current code into the “/mu-plugins/” directory and on uninstallation, remove
   the code (standard cleanup).

 * Yep, this is an option, but I’m reluctant to complicate what is a massively simplistic
   plugin with filesystem actions.
 * For all sites I’ve used this on, I’ve not need to make it MU and it’s worked…
   I think MU is probably needed in the minority of cases.
