Snape and Quirrell (was Snape, Lucius, and missing DEs)

I don't think we can assume that Snape revealed so much of 
himself to Quirrellmort as all we have to go on is the dialogue on 
page 226 of SS.

"'Have you found out how to get past that beast of Hagrid's yet?'
'B-b-but Severus, I--'
'You don't want me as your enemy, Quirrell,' said Snape, taking a 
step toward him.
'I-I don't know what you--'
'You know perfectly well what I mean.'
An owl hooted loudly, and Harry nearly fell out of the tree. He 
steadied himself in time to hear Snape say, '--your little bit of 
hocus-pocus. I'm waiting.'
'B-but I d-d-don't--'
'Very well,' Snape cut in. 'We'll have another little chat soon, when 
you've had time to think things over and decided where your 
loyalties lie.'"

For all we know this could have been a set up to get Quirrell to 
tell Snape that he was in league with Voldemort.

Its especially suspicious because of the situation Dumbledore 
put the PS in. I mean that if Dumbledore's intention was really to 
keep the PS safe why couldn't he have simply surrounded it with 
wards and hidden it in his office? But what he did do was keep it 
in the third floor corridor past a series of tests, not even real 
obsticles, but *tests* that one would need to pass in order to get 
to the stone, not to mention that the door was opened by a very 
simple unlocking spell.

Isn't it possible that Snape was under orders to seek out those 
who may be out to get the stone for Voldie by playing the friendly 
neighborhood former DE? And with that in mind isn't it possible 
that Snape did not, in fact, reveal anything about his spy status to 
Quirrellmort?
