Really cool post, Greg - thanks. That's a neat application of Twilio.<p>I'm almost more intrigued by this write-up as a study of advanced planning for multiple triaged failure modes and remote correction. It can be difficult to break out of the "ship code, find a bug, ship a patch" cycle long enough to realize the power of a few well-placed remote management hooks that can keep an app on course with minimal intervention.<p>(Also, as one who's been to my share of swim meets, this sounds invaluable for such a large competition. I'm sure folks appreciated it!)
