I wrote my own meshing software using the CGAL libraries, I would like 
to use VTK files if possible as they are what I know the best (although 
I don't know it that well). It would be easy for me to create a mesh for 
each subdomain, would it be possible to have libmesh put them together? 
But, this doesn't seem like the best solution.

Any other suggests are welcome, it seems to me that ideally each 
subdomain should be contained as a "piece" in the VTK format (am I 
correct in this, or is there another preferred method). If importing 
pieces or element id in some fashion is something that libmesh could use 
I could likely add that functionality, if it isn't too difficult.

Thanks,
Andrew
