Here's some related stuff on slashdot:

wondershaper? hmm...

| Originally part of the Linux Advanced Routing & Shaping HOWTO
|
| Before, without wondershaper, while uploading:
| round-trip min/avg/max = 2041.4/2332.1/2427.6 ms
|
| After, with wondershaper, during 220kbit/s upload:
| round-trip min/avg/max = 15.7/51.8/79.9 ms
|
| * Download version 1.1a, released 16th of April 2002.
| * Download version 1.0, released 5th of March 2002.
|
| Works on Linux 2.4 & higher.

| Goals
| I attempted to create the holy grail:
|
| * Maintain low latency for interfactive traffic at all times
|
| This means that downloading or uploading files should not disturb
| SSH or even telnet. These are the most important things, even
| 200ms latency is sluggish to work over.
|
| * Allow 'surfing' at reasonable speeds while up or downloading
|
| Even though http is 'bulk' traffic, other traffic should not
| drown it out too much.
|
| * Make sure uploads don't harm downloads, and the other way around
|
| This is a much observed phenomenon where upstream traffic simply
| destroys download speed. It turns out that all this is possible,
| at the cost of a tiny bit of bandwidth. The reason that uploads,
| downloads and ssh hurt eachother is the presence of large queues
| in many domestic access devices like cable or DSL modems.

nifty... will have to try it sometime.
