(As of December 2009), the proposed Jingle specification had not yet been approved by the XMPP Standards Foundation, but is now a Draft Standard, meaning: "Implementations are encouraged and the protocol is appropriate for deployment in production systems, but some changes to the protocol are possible before it becomes a Final Standard."[2]
The libjingle library,[3] used by Google Talk to implement Jingle, has been released to the public under a BSD license. It implements both the current standard protocol and the older, pre-standard version.
