Parent article: Bringing Signal to the desktop

Thanks Nathan for the article.

As with all of OWS's projects, of course, the source code for Signal Desktop is available on GitHub.

From my understanding the redphone-server source code and therefore the signal-server source code is not available under a Free Software license. Or can you or someone else point me to it?

But the desktop client, once released to the public, will not require using Google Groups,

Do you or someone else know if it will be possible to run it without a Google Account?

I think this is it: https://github.com/WhisperSystems/TextSecure-Server

There doesn't seem to be a lot to it: just things like mapping phone numbers to accounts (the accounts have the public keys). Signalling between phones seems to be handled by GCM, which isn't surprising. The phone side is done using RTP peer to peer, so there isn't much to the server.

The client side source for redphone on Android is here: https://github.com/WhisperSystems/Signal-Android/tree/mas...
