Of course! And don't misunderstand, this is still using a blockchain, just to manage payments and record proof that transactions have taken place. That's using a tool for what it's made for. The major reason storing bulk application data on the blockchain is too expensive is because the blockchain is immutable. If someone doesn't pay their bill, there's no way to prune their data from the network. It will always be there. I intend to implement a rolling backup strategy to help prevent and inspect tampering, but I don't intend there to be a "forever-store". Thats simply data storage that's subsidized by new users.
