Steve Slawinski is in charge of the regulatory aspects of the cbsx. You can find all the cbsx contact info on the cbsx contact page. You must ask them specifically about this as for obvious reasons they do not want to turn away new members.
If you call cbsx and ask them about their current licensing situation they will indeed tell you they have been talking with the sec for the last few months on this topic and that this current unlicensed model will not be around much longer and the best they are hoping for is some sort of grace...
