This is precisely what is needed for applications in robotics, where
numerous low power processors do sensor signal processing and/or actuator
control. Multitasking is replaced by parallel distributed computing making
real time response easier to achieve with much less software overhead. 

I would like to hear from those doing work on Squeak in that direction.
