Let's hope mtrlt either holds on to his GPU kernel like it appears he has to this point, or if released, it's released to all. Anything else risks the stability of the YaCoin network.
This is indeed my plan.
A || B ?
To me both options are about the same, if everyone has a GPU miner for this coin, then it's about the same as no-one having a GPU miner. Right now we got one guy it appears, with a very decent GPU implementation. If he abused that however, it could really damage the coin, at least if my calculations and the net hash rate estimates are correct.
I'd like to learn more about the issues at N=8K before I'd feel comfortable buying up any more YAC. The fact that the GPU/CPU ratio appears to be shrinking over time could be encouraging, but even at a 10:1 ratio, there would still be very little reason to CPU mine if GPU mining somehow got out. And if it turned into a GPU coin, I'd think a much higher coin price would be necessary to justify any miners switching over their rigs to this coin for a fraction of the hash rate (after N goes past 1024). This is a very interesting coin.
