I don't want people to feel like they have to be available at the same time, and IRC may make people feel that way. I know several people who would be interested in playing an asynchronous game. I imagine the DM sets the scene, and then the players reply with what they want to do to it. When all players have reported in, the DM updates the scene. I am just not sure if it would work in a way that is enjoyable.
