Earlier quoted context omitted.
You don't think a founding coder is indispensable to your company? Are you saying that if this person decided, one week from launch, to quit, it wouldn't matter? If so, why have them on the team at all?
Web applications are a lot easier to develop. I think too many people are still applying methodologies that applied to more "traditional" forms of software development. If I have a good JavaScript hacker bail on me a week before launch, I don't think it would be extremely difficult to find another good JavaScript hacker.
That's not such a big deal with JS, but it's a very big deal when your backend is in the toilet. You may as well flush.
