"Previously, building SMS apps was hard... " Is this true? In the UK at least it's been ridiculously simple and cheap to build SMS apps for years. I've built several and the last I had up and running in an hour from start to finish. What's a little harder (for me anyway) is coming up with ideas for SMS services that are actually useful. The rest of Twilio's stuff looks awesome though, I wish they'd bring it to the UK!
