I'm sorry, but I don't see anything in this spoiler that implies in the slightest that Palptine is Ani's father.
It is addressing a difference in Jedi and Sith Philosopy.
Ternian at MF.COM has confirmed in the related Forum topic that the idea of Palps "creating" Ani is not even broached in ROTS, and that we should be concentrating on the opening quote.
It is about Palpatine luring Ani into choosing the Sith over the Jedi - the promise of power.
As a Jedi, Ani will never have limitless power.
So he will never understand how to save Padme.
A Sith's power is not limited by their understanding - with them, the quest for power is paramount, and understanding comes with the acquisition of power.
It is Yoda who works out the "Force ghost" thing.
Something he learns through Ani.
Quite how Ani passes on what Palpatine has told him without alarm bells ringing - I don't know.
Palpatine is talking about extending Earthly life.
Yoda realises somehting that has been thus far been missing in Jedi philosophy through what Ani tells him - but this new method of tapping into the midis is used to extend Jedi's spiritual life.
IMO, it will have something to do with the realisation that midichlorians are all around - they are eternal.
Thus far the Jedi are preoccupied with the midis within.
Where does a Jedi's midis go when they die?
Would a Jedi purge make more midis available to the Sith?
Can one's identity be impressed upon the midis without as well as those within?
