Yup. World of Warcraft renders it's entire UI in Lua, making hundreds of Lua-to-C calls per frame while rendering a multiplayer 3D environment. One tiny part of that is built-in chat, both text and voice.

An IRC client is just text, right? It's going to spend 99% of it's time idle, waiting for input (via keyboard or network). As as been said, you could write the whole thing in Lua.
