The idea of ​​a startup - who implements?

Sometimes you really want to hide the source from which any content is taken - it is not necessary for this to be a malicious pirate or an agent of al-Qaida, a fairly simple competition between two offices.

And imagine such a service - a certain company buys a couple of servers with thick anlim channels somewhere in Ecuador or on the Cayman Islands, and software that provides such functionality is set up on them:

• subscription service with credit card payment
• the ability under your account to specify the IP and port for forwarding traffic from any of the ports of this server
• any server that connects to this port invisibly is forwarded to your server either simply by NAT or through VPN

Thus, I’m picking up a website on my server, and I’m telling people something like hiddenaddr.ec:1234 as its address.
One person is enough to write such a system and service in the future (in the sense, to revive the server after the inevitable DDOS on it :)) Again, what claims can there be to the server owner regarding content from various law enforcement agencies if he only transmits traffic? Of course, the true "master" of any of the ports should not shine anywhere.
Or am I behind the times and such a service already exists?
