[Mono-dev] NamedPipeServerStream in Mono

There's no native equivalent to Named Pipes in Linux/MacOS, and
specially no universally accepted open source implementation of Named
Pipes to talk across to Windows Servers, so Mono can't wrap it to
offer the functionality. Better to move to TCP and sockets if
possible, if not, contributions are welcome.
Fun,
