SimpleIPC is a set of objects, server processes, and configuration tools which allow you, the software developer, to have some of your application's work performed in an external process on the same machine. You make function calls to objects in the external process as if they were local objects. "Under the covers", you're using .NET Remoting over the IPC (Inter Process Communication) channel, but you don't need to be an expert on .NET Remoting to use SimpleIPC.
