Joris GIOVANNANGELI and Pawel Dziepak both have published final reports for this year’s DragonFly/Summer of Code experience. Both of them say they want to keep working on DragonFly, which is exactly the result I want. There may be more if the other students have time. A final report wasn’t required, but it is good feedback.
Related: Joris is working on Capsicum for DragonFly and published an API document describing how it has worked/will work.
