Upgrading Hardware is of course one way to scale. I think the most benefit could occur from implementing a smart TCP congestion avoidance solution. Quite a while ago I stumbled over an interesting article or paper (can't quite remember, RFC??). Bascially it provides a easy solution for trottling and active feedback if a router is overwhelmed, which allows more intelligent routing. The theoretical speed improvement was significant.
