Interesting. But before I ask for references on ``anafunctors'' I
would like to know the following - is it false that for any (say)
topos T there exists a category C whose 2-category of internal
categories, functors, and natural transformations is (weakly)
equivalent to the bicategory Cat_ana(T)?


Best,
MRP
