interfacing with genius as inferior process

Ciao,

I am writing a Guile interface to the GNU Scientific
Library. At present, to plot function graphs I spawn
an inferior thread that runs a TCL/TK interface with
the BLT TCL extension. This allows me to plot and to
share vectors of coordinates by converting, at the
C language level, GSL vectors to BLT vectors.

In the long term I would like to use GNOME as
function plotter. I wonder if Genius can be used
like this.

There should be no problems in making Guile spawn
Genius as inferior process and interacting with it
by faking a user interaction at the command prompt.

What I would like to know is if there is or will be
a C API to convert GSL vectors/matrices into Genius
objects and then plot them. I do not want to make
Genius compute the functions for me, I want it to
just accept vectors and matrices and plot them.
