Open Source GIS Review (plus dynamic web modeling)

Aaron Racicot up at Ecotrust has recently posted his review of open source GIS software that he presented at the Oregon State University GIS Day. It's great material, providing an excellent overview of what packages are out there, what they're good for, and what they're not. He's also made some excellent posts on the OPENNR list about his work integrating open source tools in a web-based decision support tools for natural resource management.
