Yes, I did. An open hardware building system called the hexayurt.
I started in 2002, and went through years of working with shelter charities, the US military and various other groups to get the technology into the field. There are experimental units in Haiti and Sri Lanka right now!
On the way I learned a hell of a lot about how the entire mess works, and why humanitarian innovation is so slow. There's a couple of talks on the hexayurt web site which might give you useful context: "Ending Poverty with Open Hardware" and "Enabling Humanitarian Innovation."
Please feel free to drop me a line if you have specific questions, and do check out Google Image Search on hexayurts to get an idea of where they're being used most right now!
