Did Lily and James store themselves as memories in Harry?

Hi everyone, not sure if this topic has been discussed already but I 
haven't seen it.  

It occurs to me that Lily and James have stored themselves as 
memories in Harry, in the same way that Tom Riddle stored himself in 
the diary in COS.  Lily would have stored herself in Harry's eyes, 
James perhaps in his face and hair.  At the end of POA, DD says to 
Harry:

POA p312 Br Ed

"You think the dead we have loved ever truly leave us? You think 
that we don't recall them more clearly than ever in times of great 
trouble? Your father is alive in you, Harry, and shows himself most 
plainly when you have need of him.  How else could you produce that 
particular patronus? Prongs rode again last night. ... (paragraph 
cut) So you did see your father again last night, Harry ... you 
found him inside yourself."

Some time ago, someone posted (apologies, I'm not sure who you were) 
that they thought James and Lily worked in the Department of 
Mysteries as unspeakables.  I liked this idea, and it could be that 
they were researching something which could vanquish LV, which is 
why he was after them. They could have "hidden" something in Harry, 
by hiding memories of themselves in him, so that even if they died, 
he would continue to have access to it.  I don't think it's anything 
as simple as information, as that would have been shared with 
Dumbledore and the Order, though what it might be I don't know.

However, there is the point that LV specifically suggests that Lily 
does not need to die, which she would if LV suspected that she had 
been working as an unspeakable (unless she was a double agent, but 
let's not go there...). But hey, even if the details aren't right, I 
still think there might be something in the general concept. That 
is, that something has been hidden inside Harry by his parents, 
possibly contained in memories of themselves.

Is this the "power the Dark Lord knows not" in the prophecy. 

Any thoughts anyone?
