Realistic Velocity Calculation

Oh, well - not my problem this year; shove it into the "off-season projects" folder, er, file cabinet.

Not quite an optical mouse, but I know that a couple of teams have mounted unpowered omni wheels beneath their robot that are connected to encoders in order to measure distance. Syncing the data with this with an angular measurement could then determine velocity and position. I think I remember 111 doing something like this last year, but I am unable to find the thread describing it.
