Sorry, no can do.

It has to do with the Win32 stdlib being sorely deficient, and
that is what Oracle is compiled with.

Win32 has a wonderful PIPE implementation, but no access
to it from the command line.

The only Win32 tool that has pipe access is SQL*Loader,
and that is rather limited.

Things to consider:

*) Write your own set of scripts to do multiple simultaneous exports.

*) Write your own utility to dump to a PIPE, Perl or C would work.
Not having tried this, I don't know if it is a pipe that can be read
remotely.

*) Investigate the use of netcat.  It may make this possible.  It
deals with remote pipes.
