HTML5 Rocks!

It's amazing the things you can do these days with web apps! just javascript and no plugins.

I've been playing around with peer2peer web real time communication (html5 webrtc).

I was able to put together a facebook like text chatting and skype like audio/video chatting with support for groups, ringtones, echo cancellation etc. in no time.

Only the offer/answer signalling to start the peer2peer connection is done through the server. I wrote a small websockets server in progress for the push/pull signalling channel.

I've also been playing with speech recognition for siri like commands.

I'll publish the source examples soon in case someone wants to have a look at it.

Looking good Alon, WebRTC is indeed 'sexy' but why writing a signalling server in Progress when there are so many alternatives available already... works pretty well but guess you had more fun writing some good old 4gl ;)

You're right but I kind of like the idea of having progress, javascript and nothing else, if I can.

Can you use this in

Can you please ping me at skype: anuragk29

Lets get connected, I am also working on to integrate WebRTC in rollbase.

I have not worked with Rollbase, yet.

However, other than a simple signalling server everything else is HTML/CSS/JavaScript.

The project was written on Sencha at the time but can easily be ported to Kendo UI... given a little time.

If I were to write the project today I would definitely write it in Kendo. Web apps should look like web pages not desktop GUI apps, suitable for desktops, tablets, smartphones etc.

Why pay for progress on the backend. I'm using elixir (a language based on erlang, using the erlang VM) / phoenix, soft realtime communication is peanuts. I think it beats costly progress in many many respects.
