Thanks for the info, I haven't seen much about this.

When you get a small number of doubts like this one, I suggest you email Ton
or drop by #blendercoders, just to confirm you're going the right way.

As I told you, I guess the better approach may be to create internal Nurb
and Bezier pytypes, like Bone is to Armature and NMFace, NMVert, NMCol are
to NMesh.  It's not more complicate and has advantages, unless you see that
it wouldn't be the right choice here, for some reason I don't know.

3d font is a curve, I guess.

That's a good argument.  But probably it's better to wait.  When you finish
your additions/changes to Curve, you'll have a better understanding of this.
If you keep things modular from start, it won't be difficult to either add
support in Curve or split to a Surface module later.
