Have you considered integrating pip with apk? Like `apk add py-foo` would 
invoke pip to install `foo` for you and manage upgrades too. I was using simple 
script that did something similar, so I don't need to switch between apk and 
pip and it was quite comfortable.

This way it'll be only needed to maintain packages that need patches and still
python packages would remain fist-class citizens and they would be upgraded with 
system packages. Also packaged applications could declare dependencies on things 
in PyPI easily.

Cheers,
Jiri
