We use GC Team Manager as well. They have been super quick to ramp up features, and it's completely free for everyone to view the live streams (although saved videos will require a subscription for the parents to go back and look at). Scoring and streaming all done from same app.
I really want to move to this but not until it's free for viewers. We have so many grandparents and such and going to the team facebook page is just so simple.
Perhaps there will be a solution one day...
