[Distutils] Are there any plans to move to pip/wheels in buildout?

[Daniel Holth]

Wheel also has its own installer. It hasn't received as much attention
since pip gained support.

It would be good to pay some additional attention to the "[unzipped]
wheel as sys.path entry" case. It will usually work; most packages do
not use the .data/ directories for anything but scripts; these wheels
are very similar to eggs.
