This is the first I have ever heard of that board. We always look to expand our product reach but at this time I can not say we would be offering a solution to extend our reach to that board.
We do offer custom development services at the rate of $70/hr for people looking to integrate our products into those not supported.
The BBwrapper would not help you for what your looking for. An integration module would need to be written exclusively so Reviewpost would authenticate and work with Burning Board
