What you are looking for is called "unbuffer", and is an example of the
"expect" program (probably also easy to write in C, but I do not know
about one). It's in /usr/bin in RH (assuming you installed expect), and
in /usr/share/doc/expect*/examples/ in Debian (and probably in one of
these in other distros). Of course, you still probably want tee or such.
