I'm looking for a chat product to be used inside an enterprise plone intranet.
I don't want my users need to register or approve any external service (irc, gtalk, socials, etc.), so the product should take care of users integration enabling current users to seamlessly interact each other.
It would be a plus, if that product was groups aware (implicit chat rooms?)
Is there anything around ready out of the box? Easy enough to be installed/configured without any background knowledge of chat protocols as well?
Thanks, alessandro.
