One of the points of TMMM is that communication and coordination overhead is a cost and a risk and that it grows exponentially in relation to the number of programmers you have. So, you won't get double the productivity out of twice as many programmers (unless they're on unrelated projects--but more projects == more overhead as well).
200 hour weeks would be quite unsustainable, indeed. Forget not sleeping, where do you get the other 32 hours?
I was wondering whether anyone would catch on ;)
Anyway, I wasn't arguing that more developers is easier (I do believe it might be better) - I was saying that piling hours on top doesn't scale either.
