0900 my time is 2400 west coast time. No overlap there. 1700 here is 0800 west coast time. Granted, I don't leave that early from work, but not all programmers are "in the office by 9" people either. There's not a lot of overlap.

I don't doubt it's possible, and even the best solution for some people in some situations. But not for everyone.
