I like your positive attitude!

Coda, it seems, will never be a production-quality
filesystem. It will always be experimental.

But the lessons learned in its development (such as this one,
where the scaled-down nature of coda means that it cannot
realistically be scaled up after development) will surely
be very helpful in the development of future systems.
