In our application, we would like to modify the prompt to provide some 
status info. We plan to have a system to switch between differents editing 
modes, and it would be great to modify the pompt according to the context.

But I also know that our application use ipython in a very special way.

But Ferndando, how do you modify the prompt in the pysh profile ? You do 
dynamically modify it according to the current dir, don't you ?
