Once we have the platform setup using rise vision open source code for both web-interface and players, the pricing is per display or per company registering with us or generic total subscription charge irrespective of our client base ?
It's per company. Basically, you can use one subscription for your main and every sub-company. It is a little bit messy, but it works too. Because we manage all of our sub-companies, we do not need more than 1 subscription. But if your clients (sub-companies) want to do management on their own, then, I would say, they also MUST buy their own storage subscription.
