I think this is a fantastic idea and will be trying it out with some friends later!

The only issue for me is the pricing. The free tier is great for getting your feet wet but the $99 is too expensive for me to consider since I would only be hanging out with a few friends. For me, the ideal would be something in the $15-$30 range and would increase the call limit to 3-4 hours. I don't need unlimited meetings or more than 10 people. Best of luck!
