Ive done this, it is amazingly productive. We had jabber server at one place, and all 10 devs were in the same room physically, as well as the chats: #dev #dev_pvt #dev_funny #dev_offtopic #bugs as well as having a dozen side conversations, and talking out loud in the room. Never too much time blocking on conversations, and easily ignorable when working on something deep, but since physical presence is happening, anything super important can trigger an "out loud" interrupt.
