An explanation of what CyberWarfare is and isn't

Ethan Zuckerman, writing for WorldChanging wrote a very good post questioning the use of the term cyberwar, and goes far in defining what it is and how the current attacks on Georgia's networks, websites and government infrastructure are probably not cyberwar. He also provides a very cogent description of the types of attacks that are currently in use, mostly designed to prevent access to websites and servers by keeping them too busy to respond, not the glorified and fantasy realms we see in the movies of hacking into secure systems to access data and sabotage control systems. Not that these aren't attacks, just that this doesn't seem to be what's happening in current events.
