This isn't really an answer to Jean-Louis's question, but are pub/sub
nodes presencable? Yeah, I made up a word :-) so I'll define it, do
nodes send presence stanzas? Such that when I send a presence to a
pub/sub service, I get a presence stanza with my subscriptions? That
might kill a couple birds with one stanza.
