I'm looking for free (as in beer and as in commercial-use-friendly freedom) sources of stereo satellite imagery. I assume that such imagery should not be rectified since that would remove the benefits of having a stereo image pair, i.e. the geometry of the resulting images would be nearly identical.
So far I found a usable IKONOS dataset from the May 2008 China earthquake from the University of Maryland's Global Land Cover Facility (GLCF).
Do you know of any other stereo free satellite image sources besides GLCF?

These probably aren't exactly the droids you're looking for, but the ASTER DEM is constructed using stereographic correlation. Hirano et al describe the process for creating the DEM using stereo pairs.
The only problem with ASTER is that its stereographic capabilities come from specific off-nadir tasked data collection. So unless you want to shell out big bucks, you're going to have to make do with whatever stereo pairs have already been collected.
The availability of ASTER data has also changed over time, I think because its a joint USA/Japan sensor. According to this page, you can get any L1B ASTER data from over the USA for free via the LPDAAC, but L1A and non-USA scenes are only available to certified NASA users through WIST.
I hope that helps!
