You don't need a small army of developers writing code for every client. You only need DevForce.
DevForce implements an end-to-end n-tier architecture. It works by exposing a generic web service on the server that takes a LINQ expression and returns business objects to the client over the internet.
You write LINQ queries on the client and you get back business objects with your custom business logic—just like working with a 2-tier or client-server application. DevForce handles all the n-tier WCF communications, serialization, and marshaling for you.
