I think offline here means "don't open an XML stream to me" (for
whatever reason). But then the question arises: why even advertise TXT
records and _presence._tcp if you don't want to communicate?
I see that iChat supported only "avail", "away", and "dnd" as values for
the status TXT record. That almost maps to XMPP <show/> (no "xa" or
"chat" in TXT, no "avail" in <show/>). So perhaps "status" is
effectively <show/> and should default to bare presence, which is
"avail" in the TXT record universe.
Thus maybe I have changed my mind back to "avail". :)
