Ah Flask is pretty incredible. You could probably learn it and build a functional MVP by the time we get a decent answer. (And no, I'm not hinting that it'll take a long time for him to answer :)

You can turn off the console debugger though if it's making you uneasy by doing this:

    app.run('localhost', debug=True, use_evalex=False)

You'll still get the nice stack trace and code context, but without the ability to run arbitrary code.
