Good point, now that I am searching for it I cannot seem to find the code. At the same time it still does not require custom manufactured parts or circuit boards which makes the barrier to entry (and importantly price) a bit lower unless the Stanford folks setup a store. I make an internet promise here and now that if I ever build the robot I'll open source the source code to control it.
