Hey! A little late to the discussion, but I have a question. What if my application has custom chat requirements, such as only some users being able to message other users. For this we do need some sort of proxy/server in between the client and the XMPP server. How exactly should this case be handled where requirement is based on data stored outside of XMPP? A little overview/nudge in the right direction would be highly appreciated.
Thanks!
