To put a somewhat finer point on my question: I don’t suppose there is a Vola-recommended way to access live data, but rather I’m interested in a more elegant approach than simply polling their local SQL instance (which is accessible).
There are many uses for live data that don’t compete with Vola’s offerings, including letting NASTAR racers sign up for SMS results from their races, for example.
If someone has achieved this, I’d be very interested to learn about it.
