It has been done already! It was implemented in initial version. Take a look here -
http://oxart.net/plugin/oaseo ("Wide list of sluggable plugins includes Forum, Blogs, Events, Groups and Video"). At the moment 5 plugins are supported and I'm going to add slugs for all future official plugins. The only requirement is that plugin items should have title.
