CoinJoin is a special kind of bitcoin transaction which aims to improve privacy. A coinjoin transaction is one where multiple people have agreed to form a single transaction where some of the the outputs have the same value. A casual observer of the blockchain cannot tell which output belongs to whom. CoinJoin transactions work today, and they've worked since the first day of Bitcoin. They are indistinguishable from normal transactions and thus cannot be blocked or inhibited except to the extent that any other Bitcoin transaction could be blocked.
This type of transaction was first described in a post[1] by gmaxwell.
