 I don't see a problem here. Predicting the future is hard -- maybe some
 XMPP servers will choose to censor, and maybe some won't. Probably some
 firewall vendors will offer a 'filter xmpp button' (probably some of them
 do already). But whether firewall operators choose to press the button
 remains a complex tradeoff.

 Wrt the 'xmpp servers censoring their content' question: that means the
 hexchat design should consider whether it can achieve its goals with
 fewer/no regexpable "headers" in its chat setup.
