That would be true if you had to go through Python to get to Gnumeric.
We support external plugins in python, but the mechanism is straight
C.  The vast majority of our 500 odd worksheet functions are in
plugins.

We are days from a win32 build :-)

One of the reasons I joined the Gnumeric project was the irritation
of deploying analytics as an MS Excel's XLL, or even in Applix.
Gnumeric's plugin interface was designed explicitly to simplify
things like this.

Best of luck in your work,
