With any product, there is always some talk from the enthusiasts about how they could do it faster, cheaper, or simpler. Inevitably, there's a little bit of truth to both sides. Enthusiasts have been doing homebrew NAS for as long as free software has been around, but it takes far more work to put together a complete, polished solution that stands up under the stress of an enterprise environment.
One of the amusing things I like to do is to look back at the total amount of source code we wrote. Lines of source code by itself is obviously not a measure of complexity - it's possible to write complex software with very few lines of source, or simple software that's over engineered - but it's an interesting measure nonetheless. Below is the current output of a little script I wrote to count lines of code1 in our fish-gate. This does not include the approximately 40,000 lines of change made to the ON (core Solaris) gate, most of which we'll be putting back gradually over the next few months.
 This is a raw line count. It includes blank lines and comments, so interpret it as you see fit.
