[MLB-WIRELESS] ip6 vs ip4 stupid q

On the issue of DoS attacks, maybe a little arrogantly I would say a
wireless network such as this 'could' be immune to such attacks. DoS
attacks on the Internet are a problem primarily due to one reason;
Insecure / Misconfigured systems. In a smaller more controlled network
(controlled being a _very_ relative term) the primary methods of a DoS
or DDoS attack could be negated. 

For example, Ingress Routing (across _all_ routers) an extremely simple
way to almost completely eliminate any IP Spoofing. Best practice
security again across routers, and hopefully client gateways, would
prevent all but the most sophisticated hacker (ie no script kiddies)
from 0wning enough computers to launch any such attack.
