Wait a minute!  Since when is there requirement for sluggishness in space?
Would not a faster system be desireable?  Granted that present speed
on the SRMS is limited by stopping distance, and response time limited
by the bandwidth of the joint controllers, but wouldn't an overall
productivity increase be desireable?  Even a tiny bit?
