That's a good idea, I've done some work on WinVNC, implementing a different
zlib method than the one I originally did based on Warren's work.  Basically
it allows you to switch stream-encoding methods in between messages, so you
could like turn zlib on and off, or turn zlib off and turn encryption on
etc.  And that might prove useful here.
Ofcourse another alternative would just to change the zlib level down really
low when the message length is small.
