DEM generation from ASTER L1B imagery using FOSS

Some time has passed, the topic is still relevant since new software became available:

Did anyone try out the NASA Ames Stereo Pipeline (ASP, http://ti.arc.nasa.gov/tech/asr/intelligent-robotics/ngt/stereo/)? The source code is on github.

Furthermore, in the open source software Orfeo Toolbox (OTB, http://orfeo-toolbox.org) they offer "One-click DEM generation" in their Stereo Framework (announcement). In the manual, there is a chapter on "Stereoscopic reconstruction from VHR optical images pair". Did anyone try Orfeo?
