I got a response from Zach Harvey from Lamassu ( https://lamassu.is/ ). They are working on a Bitcoin ATM, and I emailed them about Devcoin. They said they are considering a Litecoin ATM first, and will consider other Altcoins (the ones that show promise) in the future. They are focussing on the Bitcoin first though (which is set to be released early 2014. So they might consider a Devcoin ATM later in the future, as long as we keep growing.
