[Zope] Status of the PTK (Portal Toolkit)

Hi. I would just like to know how far the PTK has progressed. Is the code sufficiently complete for me to create a user with individual preferences/properties yet? I don't need the whole shaboodle, user code will do me fine right now. And please CC me, I'm still not on the list :( Regards, Alexander. Who would prefer _not_ to implement his own proprietary "user with properties" code. :)
