fairlight audio accelerator

Where is BM at with the development, tech info and release of the fairlight audio accelerator? Now that drivers are included in DR15b, would be useful to know more about the PCIE card (and one would assume a TB3 equivalent for Mac OS users at some point?). Odd, we see these cards apparently available for sale, but with little tech info, manual etc. The SDI audio capabilities in particular, and which apparently may interface with other external audio IO.
Thanks.
Thanks.
