Twilio and Boxee are hosting a developer contest and hackathon where participants can combine their APIs to integrate SMS and voice calls with internet television viewing. To get started, developers can check out Boxee's developer documentation and Twilio's resources, or follow a step-by-step guide to building their first app. The deadline for submissions is April 11th, and the winner will receive a Boxee box, a Dell Netbook, and $100 in Twilio credit. The contest has been running for almost a year, and developers can submit their apps via an online form or email it to `[email protected]`.
