The Twilio and Boxee developer contest and hackathon aims to combine SMS and voice calls with internet television viewing, inviting developers to submit their apps that integrate these two APIs. To get started, developers can check out the respective developer documentation and resources from Twilio and Boxee, or follow a step-by-step guide to building their first app. The contest requires developers to package their app, complete a submission form, and email it before the deadline of April 11th, with the winner receiving a Boxee box, a Dell Netbook, and $100 in Twilio credit.
