Win32 offers some APIs that sound like it could be what you guys are
talking about here that I'm not too clear what it is.  There are some
shared memory you can reference by name, so it's as easy to use: both
applications invoke a procedure with a string-argument and exchange
information that way.  (And Win32 does support named pipes as well.)  I
mean I'm sure you know it all better than I do.  (Perhaps I'm too
clueless here.)  I could look up the Win32 APIs I'm thinking of if that
would clarify things.
