@paoloredaelli some years ago mesh networking in phones was a no-go, because it would drain their battery too quickly. Lately I was very surprised to see a Gl.inet XE300 travel router last for 8 hours on its integrated 5000mAh battery with a #Freifunk firmware with #11s + #batman_adv (and no user traffic). So maybe portable 24/7 mesh networking devices in your pocket or bag is on the table again these days.
I'm wondering what #OLPC's experience with 11s and battery life was.
