Btw.: Does anybody know the history of Spark development? Was it developed by Jive and then opensourced?
Yes, it was. Same as Openfire. Back in the days when Openfire was still called Jive Messenger they have released Jive Communicator (which is now Spark). It was mostly a one man project, but as he was a full-time Jive developer he was moving it pretty quickly forward with regular updates and fixes (Derek DeMoro). Actually Openfire was at some point almost a one man project too (based on Gaston Dombiak work). Well, Jive was a 2-3 man company in the beginning
