SmartClient Architecture for .net 2003

i jus tried out the smart client application for .net 2003.
It has client and a server. A client being a Class Library and the server a windows application.
The client downloads the Assembly using the http protocol from the target machine.

By using System.Reflection, you can executed Methods (Connect to Remote Database) from the Server. You need a ApplicationStart.exe to launch the application at the client site.

At first time, it takes time to download to your local machine, for the subsequent requests for the Dll(or .exe) it takes from its cache.
