I'm just getting into embedded development and know very little about Yocto and how it came to be. However, I wonder if this project can somehow help other embedded distributions like Buildroot or OpenWrt?
I appreciated Andy Green's comments  on the FOSDEM talks on cross-build systems [2,3]. It seems like a large effort sink for these distros is private patches against upstream. send-patches.org was to provide a common location for these patches, but it looks like not much is going on. Perhaps Yocto can help with this situation.
