The QRPC (Queueable Remote Procedure Calls) protocol is a fast and versatile general-purpose webservice protocol. QRPC can be used as a faster replacement for XML-RPC or SOAP, or it can be used for more general kinds of webservices which integrate technical and business processes across trusted or untrusted networks. QRPC brings the flexibility of the UNIX inter-process communication mechanism with pipes, signals and redirection of "standard input", "standard output" and "standard error" to the realm of webservices.
