Man, you guys all fail at reading comprehension. :p
The OP wants an addon that shows buffs missing only on himself. He doesn't care what buffs anyone else has or doesn't have. He doesn't want to be reminded to cast his own buff spells on himself or anyone else. He wants to see what buff spells he could have on him, but doesn't. For example, if he is a warlock, and he doesn't have either Arcane Intellect or Arcane Brilliance, and there is a mage in the raid, he wants to see that he's missing an intellect buff.
I'mm pretty sure that is exactly what this does... unless I am retarded
