Interesting. So this is something that would be built into the client, and happen automatically I guess?

Well there would need to be a server/host to manage all the signatures, but it could be built into a client. There is one implementation I know of so far: https://github.com/calafou/coinjoin

I wouldn't recommend using it, not sure if it's complete or not.
