It seems that Debian people are already onto something. I just saw this on debian-python ML [1] (where I'm lurking to catch things like this :)) - Robert, perhaps you should get in touch with Geoffrey and talk to him about this? IMO in the end this should end up being a PEP or at least a cross-distro agreed standard. Either way, I think we want to be part of this from the very beginning.
