Assuming you have a computer of standard power usage and such, at what generation rate (khashes) would be the minimum to be considered making a profit? Also, assume this is a part of the pooled effort.
If I wanted to, I could make a profit at ANY khash because my electricity is already included in my rent, and I must always own a laptop anyhow, Bitcoin or no Bitcoin.
Still can't be bothered with mining though, because constant fan noise is a little irritating and not worth earning a handful of bitcents.
