Makes sense. I'm not sure what's considered a high hashrate, but good to know. Any place to find more info on the fees thing and how that works?
I wouldn't even bother looking at solo mining unless you have >10Ghash at your disposal and even then it could take you more than a week to find a block if you are unlucky.
I think even 10GHash is slow these days judging by how fast deepbit ans slush's pool total hash rate is expanding. I reckon there are rig setups out there with 30 or more machines.
