The Courier Remote Procedure Call protocol (RPC) was developed by
Xerox as part of their XNS protocol suite.  Two years ago, they were
selling documentation packets which contained all the Xerox protocols
(currently published for external consumption) including the Interpress
printing protocol. Below is the contact I had in ordering these manuals:

I am unsure of any commercial implementation of Courier.  Network Research
Corp.'s Fusion products may have implemented Courier, but I'm not sure.  XNS
has lost favor among the network integrators due to the need to communicate with
government agencies (running TCP/IP), the overwheming availability of TCP/IP in 
Berkeley Unix implementations, and the incomplete (read: non existence) of
common applications for XNS. 
Its too bad.  Courier and Clearinghouse were some of the finest higher level
protocols to exist when they were published. Bill Joy of Sun Microsystems liked
them so much, he rewrote them for TCP/IP and called them RPC and YellowPages,
respectfully. Oh well, protocols marchs forward.
