Thanks for the clarification. That's hopeful. I just gave you a sample question on cost in another comment. Even a range will be helpful when soliciting academics on it.
I provided ranges in the paper. To focus in further, you will need to get actual quotes from vendors. This is because the price is completely opaque and depends on circumstances.
Oh damn. I figured it wouldn't be that easy. Thanks anyway as your write-ups have been helpful. I imagine the chip-to-chip interconnect might be, too, at some point. :)
