I called and asked. Doesn't appear they even thought about broadcasting it somehow. My question got them rolling on it, though. (My home town. Small school with 225-ish students, K-12, and most of the people who work there are either classmates or at least schoolmates. I have connections. )
As easy as it is with something like UStream, (now video.ibm.com with several price points, and a 30-day 5 viewer trial) there's no reason not to do it these days. Heck, Sutherland Springs Baptist was livestreaming their services for their ~50 members before the shooting. (I'd assume they still do, but haven't looked.)
And it's always worth asking about .edu and other organizational discounts.
