This is great. Local problems solved by local companies in an otherwise underserved market, all aided by simple tech. Twilio should be using this as an example app.<p>What I don't understand is why it took $10M of HP product to do this. Perhaps I'm not understanding something here but it sounds like they generate random 12-digit numbers, have some metadata on what that's attached to, and have an SMS-interface in? Granted they may need physical servers in the telcos, but couldn't one $1-3k bare metal postgres instance handle most of this (500M rows, majority of which have been used and won't be seen again), and some separate $1-3k bare metal SMS gateway and REST api for static pages? Or what, you scale both of those components 1-3x more? Still no where close to 100k left alone 10M.<p>I shipped a server to Haiti to power a voice-based jobs board post-earthquake. It was a single $2k Dell server with a $1.5k ISDN card -- that 1U went into Digicel and handled 16 concurrent calls for thousands and thousands of people. And that was voice!
