Dumbledore's plan to send Snape closer to Voldemort

Many poster have suggested that the only reason Snape has never been
offered the DADA position is that Dumbledore is afraid the lure of 
the Dark Arts would be too great for Snape.  Certainly this is the 
theory floated in the books and mentioned by Snape himself to 
Bellatrix in HBP Spinner's End.

I suggest there is a greater reason Snape has not been allowed to 
take up the post.  Protection.  

We know that Sybill Trelwaney is kept at the school not for her
amazing teaching abilities, but because she was the source of the
prophecy.  In the hands of Voldemort she would be in grave danger. 
When Umbridge fires Trelawney in OotP Dumbledore steps in and 
insists Trelawney stays in residence at Hogwarts.  In HBP Trelawney 
is repeatedly in DD's office threatening to leave if Firenze stays. 
Once more, DD has to protect Trelawney by insisting she keep her
position (but DD is not disclosing to Trelawney the real reason she must stay, as she doesn't even know she made the prophecy).

We are told in HBP that there really is a curse on the DADA position
since Tom Riddle applied for the position as a young man.  Since that
time, DD has been unable to keep the position filled for longer than 
1 year.  So, going back to Snape... if Snape is now loyal to DD the only way to offer him prolonged protection at Hogwarts would be to have him teach ANY position other than DADA.  Not only for the protection of Snape, but perhaps to teach Harry some valuable lessons in the mean-time?  I think Snape was allowed to accept the position finally in HBP only because DD knew that at the end of the year Snape would have to leave the castle (becuase of the curse) and that was 
DD's plan from the start.  For whatever reason the time is now right to send Snape (still as a spy) back to the fold of Voldemort.  And what better way to send him off than with the death of DD to convince Voldemort of Snape's loyalties.  

Dumbledore is truly a master-planner as I am convinced that 
everything that was planned for Snape in HBP went off without a 
hitch!
