Jive Software has released an add-on to its ESN (enterprise social networking) software that automates and simplifies the process of integrating Jive's suite with third-party systems. The add-on is based on technology Jive acquired when it bought a company called StreamOnce. At launch, the StreamOnce add-on links Jive's ESN suite with the Gmail and Microsoft Exchange email servers and with the DropBox cloud storage app.
