Around the end of 2012 I made an experiment of recording audio from getUserMedia and uploading it to a Node.js server through web socket. Just thought it might be useful for your reference so I publish the demo on GitHub: https://github.com/soareschen/web-audio-upload
The demo use very inefficient transfer of raw audio samples as JSON array containing floating points. At that time there was no audio encoder available in Web Audio to encode raw audio signal to formats like MP3 or Ogg. (only decoder was available) I am not sure about the current status of Web Audio API, but the lack of a native audio encoder is the biggest obstacle I see in making the recording streaming upload more efficient in the browser.
