Mozilla hackday

This is the result of the Mozilla's hackday after BrazilJS 2012.

The idea is to create a text-to-speech app to run on the Firefox OS.

Due to some restrictions (like audio media and cross-domain requests) we need to setup a small proxy. It is written in ruby, using sinatra and it requires ffmpeg to be installed with vorbis support.
