BTW, I added an implementation note about batch processing here:

http://www.jabber.org/jeps/tmp/jep-0060-1.8.html#impl-batch

I've relaxed my stance on batch processing -- sometimes it is a good
thing, but I think that "client" developers (note: these might not be IM
clients at all!) need to be aware of the potential problems with it
(e.g., "last published item" is meaningless if you batch publish).
