The "information highway"? WTF is this, 1995?
No... more like 480 BC. It seems reasonable to think that "Spartan" refers to "Sparta" which in turn implies (with deference to Slashdot's notably horrible character handling): "Molon labe"... which would mean in this context: "Come and get it." The reply to Xerces when he demanded they lay down their weapons was "come and get them".
The historical reference hit me right away, and if Microsoft didn't really intend it, they screwed up bigtime. Because the name of their browser is historically a challenge to "try to go through me". So...
Let's go try it. I kind of doubt if seriously attacked it would stand as they did.
