I tried running it for a while on my laptop while at home. Let it run for a week, didn't see a single coin. Calculated how long it would take to generate one on average, concluded that it wouldn't be worth it. There is teraflop GPU at work at the moment which is completely fallow, and I might be able to get some bitcoins out of that, but that would be misappropriation of resources. (It's not true, as the article claims, that generating bitcoins uses fallow resources. Computing those hashes burns a lot of juice...)
