Doubtful with IRC servers today. Although I'm not privy to the details of IRC per se, I have set up a number of firewalls in my day and have perused a lot of sockets code, and frankly, I would be surprised if anyone one this forum found they needed ident working for anything, including irc. I seriously doubt this is true any more.
It is. It's a mitigating mechanism for many types of worms/bots/whatever, since they aren't capable of poking holes in their computer owner's broadband NAT device.
