Hey, let's take it a little further ..., but still talking about
communication between GNOME( rather, CORBA) applications.

Imagine creating an instance of some CORBA object with
operations such as get() and put(), appropriately typed.
The operations need not be only two (nor they need to have these names).
And then, launching two or more GNOME (rather, CORBA aware) applications,
passing them the IOR of the "pipe" object. The application could check the
interface and the types of the operations of the "pipe" via the
Interface Repository and then communicate with each other :-).

Also, one can think of a some form of scripting, as well as some visual
techniques to do this.

Note, that such a thing is not restricted to an unidirectional, 
two-party only communication.

Yes, it is ;-) But the shell has its uses, the above also.
