Oh, that would be easier.  In my tests, I found that a vector for
spline_radius did not work for torus, and pre-multiplied the amplitude (in
the vector parameter, not using spline_scale) and then reduced the scale.
On my next go, I'll scale up the other direction instead.

I've posted a test render on p.b.i. that shows flattened slats weaving
around fixed sticks.

I think to give a less orderly result, I can start with a grid of points
that represent the intersections, and peterb them a little.  The sticks can
bend too, but very slightly, using the same technology.  I can also vary the
tension a little from strip to strip, to simulate the effect of thicker or
thinner pieces.
