The fastest XML parsers are still much slower on the client than using
EXI, for the simple and obvious (sorry) reason that EXI sends a stream
of parse events, so the parsing was done on the server.

Facebook is exploring a number of different approaches right now,
including one done jointly with Mozilla, especially in the area of
improving JavaScript performance.

I'm still hoping that EXI for JS will be a player.
