Just so you know regarding using named pipes in MC (on Win32):  We are using
externals to do the communicating.  We created a DLL based on the externals
code supplied with MC.  When I said in the quoted section above "You
read/write to named pipes the way you read/write to files" that is to say in
terms of C/C++ calls.  That is not to say you use native MC commands.  We
created commands that opened a named pipe, closed it, read to it and wrote
to it.  Creating externals is a very powerful feature.  If MC can't do it
natively you can probably do it in an external.
