Sharing the same project directory tree with webstorm & pycharm at the same time

Hello

I have a project with Python, html, javascript and php code in the same folder tree.  I'm thinking of getting the toolbox to streamline the tools so I was wondering how multiple jetbrain ide's work together.   Is it possible to run webstorm , phpstorm,  Pycharm and other ide's at the same time in the same directory tree.   

eg  I would mark myProjDir as the top level for all ide's

myProjDir/

      main.py

     main.html

     main.css

     main.php

     main.js

     main.sql

     main.db

       cgi/

             file.py

             file.css

             file.php

      templates/

             file.html

How should one go about running multiple ide's on the same project directory.   What level of integration do they have.  Is there any 'other ide presence awareness'

cheers
