I think you miss understand what I'm saying or your experiences don't match my own. 

What I suggest is not expensive and is, in effect, what most n-tier architected solutions do. I learned from a couple guys who invented data access via a stateless browser. But what do they know?

You might be surprised by what's going on under the covers of Amazon, Google and the other commodity services. 

Best,

Jerry Daniels
