What needs to be changed for this to work on main net? Remove testnet=1 ?
I know I'm late to the party with this one but, for mainnet you have to change the [test] to [main] as well as removing testnet=1

With 500GH/s pointed at it, I guess I'll be waiting a while to find out.

Aside from low hashrate, you probably better use solo mining pool (such as ckpool or kano) which supposed to offer better block propagation speed.
