Architectural simplicity is our friend when we are aiming for scalability

If the Web has taught us anything is that simplicity in the design is our friend when we want to achieve scalability. That’s the approach we are advocating with MEST and that’s what we have been saying to the Grid community who is introducing things like OGSI and WS-RF
