To mimic the mesh behavior on devices where mesh hardware is not available and make the "under a tree"-scenario possible the Sugar ad hoc networks have been added. The [[Features/Ad hoc_Networking| feature]] adds three default ad hoc networks, for channel 1, 6, and 11. They are represented with designated icons in the Neighborhood view. [[User:Erikos | Simon Schampijer]] from [http://laptop.org OLPC] has been working on this feature and has also back ported it to Sugar 0.84.
