L8r all
If you take a look at the circuit from the instructables project the guy uses a lm393 comparator to clean up the signal from the diy encoder disk, output pins 1 and 7 connect directly to the mouse chip. For variable jog speed you could place a micro-controller between the lm393 and the mouse chip, add a couple of buttons and a little software and the 'jog speed' could be anything between the maximum encoder resolution and zero :)

Not too tricky and certainly not expensive!
