Whoa, that's awesome! Are there any plans to add support for realistic 
component meshes? The ability to show someone the final product without 
ever touching a component would be awesome.

Actually, now that I'm thinking about it, it shouldn't be _too_ 
difficult to add code for; the 3D component model would just need some 
metadata to state where, in 2D space, each pin/pad is, the pinnumber of 
each of those pins/pads, a single coordinate for the vertical pin/pad 
location for all pins/pads (since it's safe to assume all components can 
fit on a plane), and a reference to the filename of the 2D footprint the 
model fits to. The default rotation for the models should be the same as 
for their matching footprints to minimise the post-processing needed, 
and from there on it's trivial to line up the first pin/pad of the model 
with the first pin/pad of the footprint. The DRC code to test pin 
alignment and model collisions also wouldn't be amazingly complex. 
Another benefit of this all is that allows a height parameter for DRC.

But blergh, now I'm rambling about something that probably won't happen 
anyway.
