Re: [ppsp] Peer-to-Peer Multimedia Answering Machine Technology

[Johan Pouwelse <[e-mail]>]

Dear Adam,
Yes, WebRTC has many links and similarities to our PPSP work.

I've been attending their IETF meetings and discussed in details with
some of the browser creators what could be done.
At this point the bottleneck is the usual I believe: development effort.

We have now a mature PPSP-compliant streaming implementation
which could be easily adapted for VOIP and WebRTC usage in
scenarios you describe. https://github.com/triblerteam/libswift/

You have time to turn your idea into a demo for next IETF?
