How to share android screen with users outside LAN?

I work as a developer from home and I wish to demo the android app to my boss. He doesn't have an Android phone, so I have to demo the app from my phone and demo all scenarios for him from my android phone. The question is how do I share the screen with him ? Here's what I tried ? 1 - BBQdroid exactly what I want but it only works in a LAN, in fact I have to specify the android local IP address i.e. 192.168.x.x 2 - Teamviewer quicksupport but it exposes all the apps on my phone and it's not live sharing, I have to keep on sending screenshots. 3 - AirDroid only screenshots, no live sharing of the android screen Please help me guys find a way to share the android screen live with my boss. Thanks
