This is not an opinion, this is a newbie question and question is that to me it looks like that Web services is resurrection of main frames. Correct me. There are no dumb questions
Well, web services aren't supposed to be as fine-grained as I believe the mainframe applications typically were (are). There's always going to be some two business partners that want to integrate their systems so you have to provide some kind of a service layer anyway -- web services just standardize the messaging protocol.
