If your goal is to communicate securely, it's preferable to encrypt using a native (and obviously open-source) application (and OS) and to avoid the browser, for the time being.

Is to meet in person in a secure place.

Whatever channel you use might be compromised, if you cannot control both ends.

If you have an Android phone, Google tracks your location (GPS, cell towers and maps-wardriving-provided Wifi hotspots at least), so it's probably easy to see who met who. Maybe they also save seen bluetooth devices.

Phones don't record conversations in the pocket by default yet, but it's not inconceivable when computing efficiency improves that recording is always on, and keyword data is saved by default. Handy if it can creates calendar markings from verbal agreements...

And with Glass, video too.

So meeting in person is getting less secure as well.

> And with Glass, video too.

Glass adds the perversion that you don't have your say regarding surveillance of society, anymore. Your "friends" will do it for you.

Only solution: Get vocal whenever you see somebody wearing Glass.

Most phones let you pull the battery out, still.

Even when they don't, it's probably easy enough to disconnect the battery on your own.

Does anyone know how to disable WebRTC in the browser ? (Apart from downgrading of course)

I assume there is a chrome Flag for it, and a config option for firefox?
