Tossed a dual 290x on that pool.
It's only using 1 GPU, I tried doing -d 0,1 but it's not working.
Showing some shares already.
yes, the miner is not able to use 2 GPUs yet. I'll code it tomorrow. For now you can launch 2 miners for one for each GPU. (sorry for that, i was focusing on having the pool working first, and left the miner behind)
