You could also do "this sort of thing" using pixel shaders.  GPU Gems  
3 has an article by Charles Loop and Jim Blinn entitled "Rendering  
Vector Art on the GPU".  They directly render cubic and quadratic  
Bezier segments (ie: without tesselation).  Although I haven't given  
much thought to extending the technique to support non-linear  
coordinate systems, but my first guess is that this is plausible.

Of course, the proportion of world-wide computer users who have this  
kind of hardware is quite small.  Hopefully this will change as 3D  
becomes more generally useful (not just for gamers).
