A championship event is about the venue. So it should not matter whether or not it has live timing capabilities. Being able to watch times as they come in from somewhere else in the world has nothing to do with whether or not the event is a well run race. If you have a child in the race, and cannot attend, my guess is your kid has a cell phone and you can get results after every run from them. If you just want race results because you are interested, the results show up that night for some events and the next day for most others on the IMD site, USSA site, or FIS site depending on the event.
Junior racing is about learning, having fun, and competing in fair races which are tailored to the ability of the group that will be in attendance. If the venue is also tailored to spectators, then that is a bonus, not a necessity.
