Mesh networking(802.11s)
So this is very interesting stuff. This adds some very cool things to wireless. The ability to extend the network with out need for special equipment. It also adds QOS ability which will help during the use of things like VOIP, plus QOS stuff is just cool!!! But there is one thing that seems to ring with this for me and that is there may be potential for man in the midde attacks if not done correctly. They also mention stuff about auto path routing, this could be very cool, but hopefully someone thinks about DOS attacks with this stuff. But then again, I don't know much about 802.11s, plus there are not standards yet, all personal musings.
