This system/service has really facinated me. (so I bump it's topic)
So far I have "mined" 0.01351106 BTC and that's just in 12 hours.
I also plan to buy a better graphics card, which will let me mine 4.5 times faster, that is, improveing from ~10Mhash/s to ~45Mhash/s which will allow me to make almost two and a half bit coins a month if nothing changes signifigently.
