I had, once the terminations are sorted, visions of a 3 to 4 foot cable, defined as a long SPI cable.
Right now, terms are not well characterized on either end and it takes some loading trickery to make a 6 inch cable work. Bertho and I spent some time optimizing it to get 30.5 megabit one way, and 25 megabit the other direction. And its now working well to a Mesa 7i90 with a 1" cable.
