In order to avoid any SSH overhead (which makes perfect sense with Docker), docker exec definitely seems to be the way to go.
Unfortunately I couldn't get it to work so far. It would be great if someone could fill in the blanks. Here is what I did (using PyCharm 4.0.4 and Docker 1.4.1):

1. Create a file named python_myproject.sh containing the following:

   #!/bin/bash
   docker exec -i myproject_container /path/to/containers/python2.7
   

   Note that the file's name has to begin with python otherwise PyCharm will complain.

2. In PyCharm's settings, under Project Interpreter, add a new local interpreter. Give it the path to your python_myproject.sh file.

This is where I'm stuck. After a quite long loading time (the throbber says "Setting up library files"), a window entitled "Invalid Python SDK" appears and says:

Cannot set up a python SDK
at /path/to/python_myproject.sh.
The SDK seems invalid.

In ~/.PyCharm40/system/log/.idea:
