Just caught this in twitter --> http://www.bitcoinplus.com/generate
Basically from what I can tell is that you're using some sort of java process to do the mining. Java is NOT great at crunching numbers, but it is excellent at being quickly and widely distributed. Someone should create a miner in flash (which I believe can access some of the graphics libraries, and maybe get into the gpu).
This is the sort of innovation that we've needed. I actually think the "official" bitcoin client will be dead soon, and in it's place will be many various deployments of it (some closed source, some open) that the only thing they have in common, is adherence to the protocol.
