It is possible: tail-call-pipeline has a variant which allows the
redirections between processes to be specified and run-concurrently+
(and other procedures) can associate Scheme ports with particular file
descriptors at the ends of the pipeline. Whether this it's easy
enough I'm not sure: in practice this kind of redirection doesn't seem
to be needed very often. See the goonix.texi file for more details.
