Have you looked at xguest? Depending on exactly what you are doing it might
be suitable for your purpose. One note about customizing the profile is that
sabayon has a couple of bugs that prevent doing some types of customization.
But that may not be a show stopper for you. xguest is set up to do
unauthenticated logins. There might be problems with giving unauthenticated
access to the network, even if it is only through firefox.
