+This is so close to working as a Prosody plugin you know ^^
+Zash: :D
+MattJ: That component function can go
+Prosody fires events now
+but verse fires "message" where Prosody fires "message/bare"
+[20:59:50] 
+Easy... don't connect_component
+hook "message/*" and presence, and whatever
+and call c:event("message", ...)
+module:hook("message/bare", function (e) c:event("message", e.stanza) end)
+as an example
+That's so bad ^^
+and override c:send() to core_post_stanza...
