Including python3 -m http.server! (I wouldn't recommend using that on
the public internet, but it can be very handy on a private intranet).

Going back to the specific case of:

"So, let's say that I have dependency "C @
https://github.com/owner/C.git@3" in project B and "C @
https://github.com/owner/C.git@1" in project A."

The recommended way of handling that would be to:

1. change the dependency declarations to be "C >= 3" and "C >= 1"
2. use `pip wheel` to create a wheel file for project "C" yourself
3. drop that wheel file into a web directory or shared filesystem
4. add `-f <URL-for-the-location-in-step-3>` to your install commands

If using `pipenv`, then step 4 can be automated by defining an
additional `source` location in each project's Pipfile.

Tools like devpi, pinrepo, Artifactory, etc can also be considered as
potentially nicer ways of managing steps 2 & 3.

Cheers,
Nick.
