Curious about this line from the article: "128bit encryption over Wi-Fi." Why only when using wifi? I'm not aware of too much bandwidth overhead involved in exchanging public keys and using AES in some kind of stream-emulation block mode.

My cynical side worries this is some kind of concession to the wireless carriers that want to easedrop on traffic easily. I hope that's not the case! Anyone know?

Oh, there were some genuine technical limitations in implementing it over carrier networks. I'll check the exact details with the team and get back to you. (Most of them are sleeping, it's 3AM here in India.)

No ulterior motives. :)

We've built SSL on our HAProxy boxes. The concurrent load one can handle with SSL on one of these boxes is significantly less than without. Applying this to mobile traffic further reduces the average concurrent load we can manage on a HAProxy box. Given how quickly we've had to scale up its a technical decision we've taken.

Eventually we'd like to have it all across.
