The code is at https://github.com/phma/bezitopo .

I'm pretty sure that no existing format will work as the native format for 
Bezitopo. The Bézier TIN surface and the alignment (sequence of combination of 
vertical and horizontal curves — what that is would take a while to explain) 
don't exist as CAD objects anywhere else AFAIK. The program will need to 
export and import DWG and/or DXF, but exporting and importing will not 
preserve the TIN structure or the spiral curves.

If you're interested, let me know, and I'll set up a mailing list or we can 
talk off-list.
