More specifically, you are limited to 65K connections for <client IP, Server IP, Server
Port>. So you could open up to 65K x 65K ~ 4G Connections from one Client IP to a single
Server IP. Binding multiple ports is easy and can be done with a single Acceptor.
It shouldn't be a problem, but I haven't tried multiple IPs, yet. Just bind() on it.
