Hi Frank,

Glad to see ISAE is not the only company which wants to combine network 
coding and webrtc.
As I said in Orlando, we integrated our network coding library (Tetrys) 
inside both VLC RTC modules.
We just encapsulate RTP packets inside Tetrys packets (application 
layer) at the sender, and do the reverse operation at the receivers.

We also work on the integration of NC in webrtc.
We saw that webrtc already integrates a FEC mechanism (you can find the 
sources in the rtp_rtcp module). We would like to estimate if NC could 
improve webrtc performance.

We will attend Berlin meeting and we'll be happy to discuss with you 
about our proposal to assess whether it is possible to converge towards 
compilant implementations.

So, we will be happy to participate to the discussion in Berlin.

Best regards,
