Thanks for the answer , some good ideas i will use.

Didnt quite found the exact addon i was looking at so i started working on my own addon.

Its basically a button addon which:

1.Displays Auras gained,Spell Cooldowns,Ability ready for all toons on a button( this will get synced between all clients running this mod ).
2.Be able to hook up macros to that button.( so f.ex a proc can light up when on in a fixed position and then i can l/rclick it to perform a macro.
3.Show as button rows , 1 for each toon and it should be placed the same on all screens( so that it is simple to create repeater regions )

A screen to show how this alpha mod works:


A video where i shows its usage , should make it abit clearer what i want to do.

This is still very alpha and not really ready for public yet , missing options dialogs , config options and sortof hackis at places , but if there is some interest in the idea of a mod like this , i can try to polish it up for a public release.
