 Makes the HTTP* service running at ADDRESS:PORT available via a proxylocal
 service running on SERVER. The default server is p45.eu, and the default address
 and port are 127.0.0.1 and 80.
 
 By default, the service will be available on a randomly generated domain name.
 e.g. 4iur.p45.eu. To specify the first component of the name, use the HOST
 argument.
+
+You can connect multiple clients to the same host name. To help prevent abuse,
+each client must present the KEY.
