Excellent questions. 

Technically, yes. However, ARMCI does more thinking about Global Arrays. Particularly because of stride data transfers (multiple stride levels). However, I don't see why we cannot have an alternative port. The only way to know is to prototype the interfaces, implement Global Arrays on top of them and see how the interfaces fare. From superficial thinking, I think they will do just fine ;-). We however cannot say this about all potential implementations. 

I am not sure if Dan Bonachea is a member of this list. I will write him a message if he isn't.
