Although kernel throttling is a good solution, I disagree with your thoughts that any of the "fancier" shaping mechanisms give you no additional features. Kernel throttling will never give you the relational shaping that class-based-queueing gives. We have quite a few machines under a class-based queueing machine and have it tweaked quite well. With class based queueing you can define "classes" of computers and define which machines have priority over others. You can also give people "guaranteed information rates" and let them burst above into any unused space. We also have ICMP shaped into a seperate class. Most of these can't be accomplished with kernel throttling. Thanks!
