I've looked into this a bit, because right now setting up Penumbra (http://github.com/ztellman/penumbra) is way too complex. As far as I can see, there are two different situations to think about: 1) A standalone executable which relies on Penumbra. This situation is actually pretty well supported by JOGL's use of JNLP, which will download the appropriate binaries at startup (and cache them for later usage). This has the benefit of being more lightweight (the jar doesn't have to contain all the binaries for all the target platforms), so maybe there's an argument for Leiningen generating the .jnlp file. 2) A library which relies on Penumbra, or any development work towards a standalone executable. If there were some generic code provided by Leiningen which did the runtime extraction of the binaries, I don't really see any issue with doing it that way. The "lein run" approach described above would also work, with the caveat that "lein swank" would also need to have similar functionality. With all that said, I'm certainly not an expert on the subject. If any of the above seems suspect, please feel free to correct me.
