sell shell accounts?

This is true. But show me a model in which this works and which can update
that forwarding table 20x/second (at full load WHILE switching packets).

That's what Netstar claims.

CISCO can't even *dream* of getting close to this level of performance.

They don't have to. They're selling routers.

Maybe when Netstar's can be deployed, there'll be something to shout about.
Until then, it just plain isn't worth arguing about.
