IRC does do polling in the form of Ping and Pongs. If it detects that a client is idle it will send a Ping response in which the client must respond with a Pong or risk being disconnected. It works very well actually. As for getting thru a firewall with IRC than most likely your firewall is allowing IRC ports to pass thru.
