I also think it'll have to be an opener or at least a #3. But otherwise I suppose any of the openers for the stronger test nations would be capable of doing it on a good day. It just has to be their day.
EDIT: And come on, of course it's going to happen against a side like UAE. I know some of the top teams in the world aren't fantastic, but I can't even see Zimbabwe allowing for a 200 to be scored against them. It would take a truely once-in-a-century kind of effort to pull off in an ODI against a decent test playing side.
REMEMBER: A couple of years in therapy, you'll get over it.
