The team continues to work on upgrades with some of the recent work on the back-end. We will announce changes as we make upgrades for users.
I am not sure I understand your question "can we direct go to the public version?". Are you asking if the current Beta version can be used by customers? If so, answer is YES. You can use this with your collaborators now. We will maintain all the data even when the beta tag comes off.
We do not have plans at this time for a 'private cloud' version of the collaboration portal.
