DEM generation from stereo image pairs in GRASS?

[David.Osborne at nottingham.ac.uk]

A collaborator on our project told me she had heard of some people using 
GRASS for deriving a digital elevation model from stereo image pairs, such as 
aerial photos. Is this possible in GRASS? I'll be using a few other packages 
to do this (ERDAS OrthoMAX, PCI Easi/Pace, and 3D Image Maker) and comparing 
the resulting DEMs, so GRASS would make another interesting comparison, if it 
can be done. The images are Shuttle Large Format Camera frames.
