Yes, this will prove valuable (for other things than dlls, admittedly).

We control our environment and package only what is needed in it. This makes a micro system in which everything is controlled and isolated, even the global dlls (to the virtual env) I wanted to install. They become only accessible to the activated environment. I don’t see how it can become DLL hell in this situation. 

But hearing many fine and useful comments on the thread made me change my mind and package the dependency near the extension module.

I still find that something like pep 459 will be really useful.

To the list: Thanks for all you input.
