Very cool! I’m glad you’ve had good luck with this!

Thank you for your great post. You inspired me to try my hand at etching and design. I used your design as a base and modified it. Check out the details here http://www.3dprintmd.com/print/nanino-share-alike/ To summarize what I have done.

Original (where I got it from) http://www.meatandnetworking.com/projects/nanino-upgrade/. I actual original came from http://vonkonow.com/wordpress/2012/10/nanino-the-diy-friendly-arduino/
I added a 5v voltage regulator and supporting caps.
I added a 2 pin header for input on the unregulated side of the voltage regulator
I made the board two sided. Previously the traces on the top were wires. It will still work as a one sided board if you desire.
I added copper fills to the entire board.
Added registration marks for aligning the top an bottom
Added the name and version as a copper fill. I used version number 5 arbitrarily for my own tracking purposes
Standardized all holes to size #65 for easy drilling
Increased all pad sizes to .075 for easy soldering and to resolve pad lifting issued when soldering

I don’t have a good picture of the final product from the solder side, but drilling and soldering were trouble-free. I had correctly-sized drills, and aside from using the wrong drill size for the pin headers (at first), it wasn’t a problem to get a good drill hit with enough copper for a good solder joint.

This may vary for someone else’s process, however, so it’s still a good suggestion.

Having done this kind of thing myself, may I suggest making the pads quite a bit bigger? The etching step has obviously gone well, but when drilling and soldering, you may find the pads are too small. Take a look at the PCB I did for an ATmega32:
