Creating a Custom Post Type Template MU Plugin

One of the great things about the Custompress plugin is that it defines custom post types, fields, and taxonomies community-wide.

But, to show fields or more advanced post-type creations, I need something more customized than single.php.

I’d like to pop plugin into mu plugins that creates a single-custom-post-type.php template on all blogs. Looking around the web, I haven’t found anything to help me out.

The template itself is easy coding. I’m just not sure about the rest of it.

Anyone have any insight or ideas?
