[Distutils] Packaging multiple wheels in the same archive

As part of working on Cloudify (http://github.com/cloudify-cosmo) we've had
to provide a way for customers to install our plugins in an environment
where PyPI isn't accessible. These plugins are sets of Python packages
which necessarily depend on one another (i.e. a regular python package with
We decided that we want to package sets of wheels together created or
downloaded by `pip wheel`, add relevant metadata, package them together
into a single archive (tar.gz or zip) and use the same tool which packs
them up to install them later on, on the destination hosts.
We came up with a tool (http://github.com/cloudify-cosmo/wagon) to do just
that and that's what we currently use to create and install our plugins.
While wheel solves the problem of generating wheels, there is no single,
standard method for taking an entire set of dependencies packaged in a
single location and installing them in a different location.
We thought it would be a good idea to propose a PEP for that and wanted to
get your feedback before we start writing the proposal. Our proposed
implementation is not the issue here of course, but rather if you think
there should be a PEP describing the way multiple wheels should be packaged
together to create a standalone installable package.
We would greatly appreciate your feedback on this.
