Dock auto hide/show scrooll speed?


Does anyone know how to adjust the in/out scroll speed & sensitivity of the dock when it is set to auto-hide? I'd like to use auto-hide, but I only want it to appear when the mouse actually touches the bottom of the screen. Then I want it to snap open. As it is there is too much of a wait for it to open. What would be REALLY cool would be to have multiple docks across the bottom with their own tabs, and to have the docks have the ability to hold shortcuts to files and directories (not just applications). the dock is a thing of true beauty, but if its functionality were expanded, so would its value.
