Yeah, you're right... those folks over at Jabber.org just aren't on  
top of things. ;)

More seriously, we've just been talking about s2s and the fact that  
anything supporting s2s can, in theory, support MUC by virtue of  
using other conference servers.  Maybe I have a reason to join a  
private chatroom on a private XMPP server, for some project I'm part  
of, but that server goes down for maintenance.

I'm still up on my own server, but s2s to openfoo.org (and  
conference.openfoo.org) is down, and thus I don't get a caps for  
devtalk at conference.openfoo.org, and it shows as just an offline  
contact in my list.  I can't display UI to the user of 'this is an  
unavailable conference room' if they click on it, because I don't  
have the data that it /is/ a conference room.  Thus, I cheerily send  
an offline message.

<item jid='stpeter at jabber.org' name='stpeter' subscription='both'/>
<item jid='devtalk at conference.openfoo.org' name='DevTalk'  
subscription='from' category='conference'/>

The first one, lacking a category, has an implied category of 'client.'
