I know some time back there was a project with chatting in Jeuno via someone's mule. All the shouts and say got posted on a website and you could type things in to have the mule say in shout. It would be pretty neat if we could have a cell phone app that lets you interact with a populated area in shout if you have a character. I guess it would be too easily abused but it would be great fun... even if we couldn't interact just to see what people are saying in town when you're bored but can't log in.
