This should be possible.

It is a c++/python wrapper around Triangel 
<http://www.cs.cmu.edu/~quake/triangle.html>, for 2D meshes and as allready 
mentioned tetgen for 3D meshes, called TriTetMesh.

It saves meshes in the format possible from these two libraries, in addition 
to dolfin. You are also able to set markers to vertices, segments and, 
triangles for 2D and, in addition to these also for tetrahedrons in 3D. This 
information is then written to appropriate Meshfunciton files.

I will just give the code some final love and then I can share it. Thanks to 
Anders for good comments on the usability :)

Cheers,

Johan
