Re: plugin-template.php
Well, we got a couple of options here.
1) hack the theme and git rid of the content div in the header.php. That means changing all existing templates that rely on that content div being gen’ed before it gets to them 
2) hack the directories and all other code that just assumes that they are responsible for gen’ing their own content divs and leave the theme header.php alone
3) get a different theme
