Isn't this easy to do?

Our goal is something like:

//w resides on some other machine
Widget w = new Widget();

//this function is executed on that other machine.
w.calculate();

• In order to do achieve this small miracle we need many things.
• We need a protocol for creating new objects remotely, invoking methods on them, getting the results back, and deleting unused objects.
• In order to do this we must send
  • Class references
  • Object references.
  • Method references.
  • Method arguments and return values.
