Just on this topic, suppose I want to activate silently virtualenvs if 
they exist,
I thought to this possible solution.

- start a python script with the standard python interpreter
- lookup the project virtualenv, and create it if it doesn't exist
- run another subprocess which is actually what I want with the
   virtualenv interpreter, forking or substituting my original process

Makes sense?
Only the last part seems a bit tricky, if I just substitute the 
python_executable
at run-time I'm not sure it might be enough..
