Here's the situation - I share my connection with other people, and even though it's broadband, it's a fairly small pipe, especially upstream. What's happening is that when I'm gaming, somebody might decide to start downloading stuff or browsing or whatever, and that completely kills my latency. I've approached them several times, but they just deny they're downloading anything at all (Even though I can see the porn window minimized) and refuse to stop. This brings me to my question: Is there some inconspicuous way I can limit the amount of bandwidth they use? I've checked my router specs, and I don't think it supports bandwidth throttling, so it'll probably have to be something software based.

Yes, you can artificialy limit others bandwidth. Talk with a network engineer about how to setup such a system.

Some routers (especially the WRT54G 4.0 and earlier, WRT54GL, etc.) can have Quality of Service functionality where it'll prioritize various pieces of data ... like your game.

What sort of router do you have?

Edit:
It occured to me that some routers also have filters, you could attempt to simply block the porn they're downloading. Most routers, I believe have url and keyword blocking.

A Netgear FVS318. I've already checked, it doesn't support QoS or bandwidth throttling.

Most of your bandwidth aggregation utilities falls under QoS. You'd need to buy a new router. It will say on the box if it's QoS. Although with the way Cisco pushes QoS like it's going out of style (go to any Cisco tech meeting and you'll hear the phrase about 9000 times), I don't know of one newer Linksys router that doesn't support it.

EDIT: Have you checked Netgear's site for a firmware update? I doubt it would add Qos, but you never know.
