I'm sure there is and will be demand for good static IPv4 tunnel brokers. I'm personally fine with dealing with dynamic DNS and port forwards for my home setup for now, but once I no longer have a public IPv4 assigned I would be a potential customer.

How do you deal with the global scarcity of IPv4-addresses that you would need to scale your service? I think this can only work long term if you own the address space yourself and are not dependent on some specific provider or cloud.

Also very important is a local endpoint to get a reasonable end to end latency.
