I suspect, even if the hardware was open sourced and fully available today, I doubt the current load would warrant it's use. And I also think, if the hardware acceleration was enforced at dash's current price, a lot of MNOs would simply sell their holdings and go elsewhere. There needs to be a compelling reason to implement it, especially when comparing against the demands and performance of other blockchain projects.
i guess u are referring to Evans comments from some time ago
there is nothing in planning or production so far , DashLabs is working on many things (as far as i know) but there is nothing concrete in the making (and no HW coming as far as i know )
agree with Grandmasta, no need for that anyway yet (not enough work being done by MNs imo)
