Indeed, "real-time" is one of the most requested features for S3stat, even though there's really not much you'd be able to do with faster data. In our case, Amazon doesn't even deliver their logfiles until 8 hours or so after the fact, so "real-time" reports would just be a pretty moving picture of the past.
I toy around with the idea of building it out as a feature anyway, just so that I can charge a premium to customers who want to turn it on.
It's what news orgs have been doing for a long time. The number of people addicted to this crap is much more than the number of people who can do something useful with it.
Why that is, has more to do with psychology and evolution of the mind than it has to do with the actual real time data or news.
Eh. Now that you mention it, watching an optimizer battle out a 0.1% objective function improvement every couple iterations on a run that took a few hours total ...
(But that was in another job, and besides, the code is dead.)
