ah yeah, i forgot that was what it meant

there's a lot of very fast SHA256 mining hardware that can be applied to this, so what i said about it being ded multiply that by two orders of magnitude

sure, most current generation miners can't be persuaded to hash anything other than 80 bytes but there is still pretty fast ones that can be reprogrammed, you have to implement a sponge function either way and the limitation is just a question of how you write the firmware, mostly
