Nice idea!  :)

This depends on what you want to display. If you want to display some 
stream metadata (like title, length and current position), you would 
just have to include that into frontends, possibly making this a 
separate library so all frontends can benefit from this.

For such things (non-metadata, but depending on the actual stream), post 
plugins are indeed the best solution.

That should be no problem. Post plugins are (or at least should be, 
beware of bugs) fully cascadable. Something like this

The xine hacker's guide is always a good point to start. Unfortunately, 
the section on post plugins is still missing. Blame me for that.
