Very interesting. How resistant would this be for hosting legal but controversial stuff? And what's to stop the peergos.me from dropping the said controversial subdomain?
Peergos.me is just one public gateway, and yes it could block whatever it wants or be blocked by DNS, but anyone can run a gateway, locally or publicly. Ideally in long term, browsers end up supporting the protocol and then the gateways can be turned off.
It's static websites only at this point.
