More speed would be awesome!
Some of my projects would benefit from increased speed. For example my 
"stromverteiler":   
http://elektroniq/index.html/lib/exe/fetch.php?media=eigenbau:stromverteiler:stromverteiler_v1.pcb
On reasonably current hardware (pentium P5, haswell), the benchmark() 
yields about 5.5 FPS for this layout with all layers activated. Yes, this 
is the most complex design I ever did. But it is a real world project :-)

Well, I still think import/export to freeCAD would be way more useful than 
reinventing 3D wheels inside pcb. The license issues connected to the 
opencascade lib used by freeCAD have finally been resolved. :-)

BTW, the freecad website has come a long way since I last checked:
	http://freecadweb.org/
I hesitate to compare this to the current state of the geda-project.org 
website...
