[JDEV] Promiscuous presence for user communities (with patch)

[Peter Saint-Andre]

Hi Steven,

First, it is already possible to do "promiscuous presence" in jabberd 
1.4.2 using the "presence bcc" markup in the jabber.xml configuration 
file -- see the release notes. This feature pipes all the presence off 
to another JID (usually a component), which can provide an API for 
sending presence out to whomever you please.

Second, you can't just add new presence types to the protocol. :-) This 
protocol is now in IETF Last Call. Just as you can't add a new HTTP 
method because you think PUT and GET are not enough, you can't add new 
presence types willy-nilly.

I agree with you that community building might require something like 
this, and putting that under the control of the user is good. But I 
don't think that a new presence type is the best way to make that happen.
