Hehe...

Consider the outlook of technology now, x8086 demo for example. There is 
a good chance the vector ops will be more of a superset of instructions 
rather than a subset, as they are with Opteron, Xeon, Pentium, etc. I'd 
imagine the vector ops can easily have a dynamic stride by then with any 
available processor on a parallel core to execute the next element until 
all elements done. =)

Thanks for your insight
