One of the important points is that the feedback from our sensory system is noisy, I haven't seen this implemented in many A-Life programs.
Of the popular A-Life programs I've seen (avidia, Polyworld, Framsticks and breve), the focus of the program is often on developing some sort of adaptive movement (depending on the fitness function). Polyworld is only concerned with gross movement, but (more naturally) uses reproduction as the fitness function. Framsticks and breve allow multipart bodies and finer movement, but, to my knowledge, have "non-reproductive" fitness functions. Is it possible to combine the two (programs or neural nets) into one.
On a somewhat unrelated note, it may be that we have brains partly because we need to move, but brains also seem to be very good at pattern matching (both spatial and temporal -- and in ours abstract). Since there are very simple creatures which move but have no brains, I would suggest that "patterned/adaptive movement" is the reason for brains.
