X is analagous to Amanda in that its a matter of defining the
important resource.

In X its the SCREEN, not the CPU cycles that are important.

In amanda its arguably the central control, work area and
tape drive. Anything the clients request is a secondary effect
to the server initiation the process on the client anyway.

It can be argued multiple ways - and I'm not trying to start a
(pointless) war, just hoping to shed some light on the "resources"
in question and the accepted terminology of this particular domain.
