This is really close to what I am doing. I've to shorten my code a lot
to get it posted here, but basically this happens:

def home(req):
    sess = Session.Session(req)
    if sess.is_new():
        # get settings from cookies (using Cookie)
    # page built up, using sess["language"] for the language setting.
    sess.save()    
    return apache.OK

def english(req)
    sess = Session.Session(req)
    sess["language"] = "en"
    sess.save()
    home(req) # to redraw the main page

And same for other languages as well.
The page uses a little PSP to easily set some variables, no code in the
pages. It appears to hang on the Session.Session(req) call in the
english routine.
The english routine is called through a hyperlink off the main page (a
href main.py/english).
