So stay tuned. However, the proposal > concentrates mainly on allowing several ports to build in parallel. I do have a script/Makefile ready, that can be used to build several ports in parallel (taking inter-dependencies into account). It _could_ be hacked into the current ports infrastructure, if we augment INDEX with additional fields. It is aimed mainly at release building/pointyhat but comes with almost no software requirements (screen and zsh are the only external tools). I'm having some problems with unionfs though, and need to implement two different strategies first, before releasing an early version to the public.
