Comment:

 Well..  The *ping* case is debatable..   the reason the ping was becoming
 annoying is my xmpp server doesn't implement ping and the log was filling
 up with all the clients pinging it (which are all pidgin on various
 platforms).

 Others were entity-time and vcard-temp which I ended up implementing in
 the jabber server.

 other DEFINITELY should be checked before.. and I could see ping as an
 eclusion for the sake of a keep-alive.
