First of all, let me to add to the bibliography a nice book
we have just got:

Sheaves in Geometry and Logic,
By S MacLane and Ieke Moerdijk, Springer.

Second, I want to ask if some Topos/Sheaf fanatic have studied
relationship between the generalized spaces etc of Topos theory,
and the non-conmutative "spaces" of Alain Connes. 
Im not expert in the matter, so I could be asking a nonsense. 
Anyway, a motivation for the question is that the Kroneker
foliation of the bidimensional torus, which were the main example
of Connes' theory, is also one principal example of Sheaf/Topos
theory when used to calculate De Rham Homology. At least, it is
used by Moerdijk (althought not in that book) to show all the
constructios of clasifiyng topos, BG etc...
