Currently I don't have an integration/mod for Xenforo, but it could be done just in the same way it is done with vbCredits.. However you would need a developer that knows something about Xenforo (and has bought a license for it, we don't have one), to do the actual work for you.
Essentially the idea is that you are adding a poker lobby link (popup) or iframe window to your forum, and the URL is from our website. You add the logged in user's username and password (you can MD5 the password if you like), and then our system automatically registers the player or logs them in depending on whether they have been seen before. So the end result is an apparently seamless integration with our system, where the players don't have to register separately.
The easier option is just to put the popup link of your rented game lobby into your forum pages somewhere (if you can add a simple custom link to your main page?) and then tell players to register separately. Our system tracks points/credits, the problem would be integrating with YOUR point/credit system though. We have an API where you can pull/push player points, but that comes down to having a developer again..
