Before I found out about traffic control in the Linux kernel I used the rshaper module: http://freshmeat.net/news/1999/11/02/941520726.html. You might find it useful to drop packets. The rshaper module shapes incomming traffic depending on the destination ip address but it is easy to change it to only drop some packets according to a drop function. If you are unsure about how to make the necessary changes to the module I might help you, if you provide me with the algorithm for the packet drop function.
