I believe these results (which was= from about that many machines and there were some good data being presente= d and crunched) were using multiple channels and diversity routing, which i= n the b.a.t.m.a.n world
is called "interface alternating"

As I recall= OLPC now has two radios?

The distributed arp table landed in the mainline linux kernel fairly re= cently
