With the ebb and flow (or initial flow, and precipitous ebb) of Dante discussion around here, I'm hoping that the growth in Dante implementation across commercial products might lend itself to some good old fashioned reverse engineering. Take, for example, the Dante-X card available for the Behringer X32. It's interchangeable with the USB interface, and on first blush (based on the pinout of the connector) looks to be doing little but routing the i2s to a Brooklyn II card via FPGA. It must be a fairly agnostic interchange between USB and Dante, considering that the Dante docs state that their cards take in i2s streams. I'd love to tackle this one solo, but my assembly coding is pretty stale. Calling Andy Peters?
