Both of those sound like interesting options. Something like E2C might 
be easier to set up (we'd need some more work to split the large data 
sets for a distributed rendering system).

EC2 (or something equivalent) might still be a significant cost, though. 
Looking at the EC2 x-large vm specs, it seems to be about 5-10 times the 
speed of my quad-core rendering server. Import, preprocessing and 
rendering (almost entirely CPU-bound) took just under a week, so it 
might take, let's say, 20 hours on the EC2 wm, or about $20. In that 
case 50 states (assuming approximately equal size) would be $1000. Per 
rendering.

Either way, I guess the thing for me to do would be to clean things up 
just enough to be readable and then put the code and instructions up on 
the wiki. Then we can all play with it. :) I'm right in the middle of a 
move, so it may take a bit longer than otherwise, but I'll do my best.
