What about the following principle:

 - Every plugin (actually the methods in there) acts as a filter. Content
   towards the backend is filtered, content from the backend is filtered.
   (This is pretty much how I think it works now.)

 - If a plugin does not want progress, it raises an exception.

 - The precedence of plugins must be controllable, say

    ->plugin_a_before_b (a => $plugin1, b => $plugin2);

Would this break things horribly?
