Kruthal, nice summary. However I think that there should be a menu that lets you to either choose or define the debuffs you want to display (Power Auras style?) as there might be certain abilities you want to be displayed for a certain boss (either already implemented in the game or future one - Viper Sting for example).
Actually, all the addons metioned above (ClassTimer, Debuff Filter and Power Auras) are almost what Praet wanted but always fall short in certain areas.
ClassTimer - class specific but has great options to set the view the way you want (in my opinion Wodahs' suggestion is briliant - you could set up a list of debuffs and they would appear active/inactive in accordance if such a debuff is applied to a target/focus)
Debuff Filter - lets you see the debuffs you want but the order is "random" and you have to search the debuffs you still want to see applied - lack of organization (is non-ace2 a hindrance too?)
Power Auras - I suppose icons of debuffs rather than auras are the requirement for this addon.
My idea of how the addon should look like spakled from the screenshot Souja posted in the Any cooldown forum. Debuffs in a line with a timer on how long they will stay on (Souja's picture has this for his own cooldowns).
