One way forward in terms of building wheels is to use any build process you like to do an isolated build (I think it's --root that distutils uses for this sort of thing) and then use distlib to build a wheel from the resulting directory structure (or do it by hand, it's not much more than a bit of directory rearrangement and zipping things up). That process can be automated any way you like - although ideally via something general, so projects don't have to reinvent the wheel every time. If processes like conda then used wheels as their input for building packages, the wheels could *also* be published (either on PyPI or on a 3rd party site such as binstar) to provide support for people not using conda for their package maintenance. There may be technical issues with this process - not least, does the way conda uses shared libraries make going via wheels impossible (or at least make the wheels unusable without conda's support for installing non-Python shared libraries)? But it does remove a lot of the duplication of effort and competition that currently seems to be involved in the conda vs wheel situation. In this scenario, there are two binary formats - wheel and conda (the format). There are a number of packaging tools, notably pip and conda (the tool). Other tools and/or formats can be built on the wheel binary format to address specific communities' needs, much as conda does for the Scientific community. Here, wheel and pip are the bottom layer, the Python specific binary format and package manager. They are appropriate for people with generalised needs, and for communities with no need for a more advanced/specialised tool.
