[pstricks] lines perpendicular and tangent to a bezier curve

Hi all,

so far, I have something simple like:

it looks like with the "ArrowInside=-|" command, it is possible to have 
access to a line which
is perpendicular to a bezier curve for a given intrinsic parameter with 
the "ArrowInsidePos" parameter.
I would like to have these lines more flexible in order to make them 
arrows or whatever.
The same with tangent lines would be great!
Is it easy to implement?

I had a look at pst-thick as well but it handles function-like curves 
only (nothing like psbezier or pscurve, unfortunately).
