Nope. Tiered applications and REST are not the same thing. REST only defines constraints on how to handle identifiable resources. It doesn't care whether you are trying to use a thin or thick client. It only cares about the resources. You could have *all* of you business logic in the client (with none on the server) and it still wouldn't matter to REST. Note, however, that complex RESTful applications are difficult to implement in a browser without using Javascript, Java, Flash, etc. The very fact that browsers only support two HTTP methods is an indication that they are not suited (by themselves) for the sort of thing you want to do.
