>The Remote Procedure Call component of DCE allows one to call a procedure
>that may be local or remote or both. The ideal is that the 'right' box for
>the procedure returns the results to the calling box. If there is more than
>one good box available, either the ostensibly fastest box answers the call,
>or it is even possible for more than one box to take the call, and the box
>that returns the results first wins. DCE can let one configure the involved
>boxes for any of these scenarios.
>
>DCE also include components to support the POSIX spec for kernel threads so
>your apps can be muli-threaded, organization of boxes into groups called
>'Cells', time synchronization within a cell, and a security component.
>
>My own thought is that this is a more elegant metaphor than client / server,
>since in a complex enough operation, a given box can both serve and be served
>other boxes.
