It's all part of the same problem domain; How do we rearchitecture the release process of Arch so we can support multiple architectures.
The amount of people that understand this problem domain, have the time+energy to work on it and is actually able to see it too completion is.. well. Not many.
I tried to hack on buildbot, as I wrote in that email, but I have been questioning the maintainability of trying to fit what we need on top of buildbot. In constrast to writing something from scratch.
