Perhaps, Mike, I'm missing what you mean by your "wish" for 2d to 3d 
extrusion, but in addition to the height field technique Stephen 
mentions(1), Inkscape itself has a POV-Ray export to POV-Ray's 3d prism 
object. The export worked OK(2) a couple years ago when I tried it and I 
know Thomas has worked with it too for his Gancaloon project.

Maybe though, you want specifically a 2d to 3d-closed mesh on the fly?

(1) - Something similar to height_fields can be done with isosurfaces too.

(2) - I did see an issue with something like redundant points, which 
caused POV-Ray no issue, but did trip up another program in which I 
tried to use the bezier spline output.
