>It's the logical n-Tier design work that will give you the flexibility, not the coding. Separating the logic and dealing with state issues in the design leaves you able to implement it in any language or platform of the future.

So what your saying is its flexible enough to keep the pretty diagrams about how it should work, but not flexible enoguh to actually reuse any code used in the app?

If thats totally wrong, can I have an example.
