There is a difference between the projects and published articles.
The articles students write and publish should be more accessible. Computer Science programs are more liberal in this generally because the CS students and departments nearly always put the articles and papers on their web sites for a time.
The projects they create, however, are a different story.
Many times the projects serve as a springboard for further research. At graduate schools the projects tend to grow for many years and spawn into many future projects.
When I attended graduate school I was studying graphics and I was employed as by the school as a "research assistant". Those projects belong to the school, just as my projects today belong to my employer, but they were also projects created by students for use in their courses.
(Strange how I still think of it as "our lab", even though I haven't been a student there for many years.)
Our lab had sold many of our creations.
The "Magnetic Lasso" in Photoshop and "Intelligent Scissors" in GIMP both came from the same family of research projects in our lab. There is still much active work in interactive segmentation and editing.
Google Maps has ties to the lab's terrain research, where in 1998 we were publishing papers like "Interactive Display of Very Large Textures" that worked much like Google Maps, adding heightmap rendering but not as much as Google Earth.
We've had handwriting recognition techniques, "Live Surface" medical visualizations, automated generation of 3D models from photographs, and much more.
Many of these projects have been sold or licensed for considerable amounts of money.
And that is just from one lab. The CS department has many, each one creating very useful projects by students as part of their studies.
Papers? Yes, release them. This helps further future research and is funded by many sources. Papers are the condensed knowledge and are very valuable to outsiders.
Projects? No, keep them. The implementation details are less portable than the research papers themselves, and the projects help future research at the school.
