Yes, this might cause a slowdown... If I ever noticed a slowdown I would have stop watching youtube and video. Even, others might not, though. I see your point. I am not intending to download as a maniac, so I limited some downloads to 30 kb/s, but I don't know if that is enough. If we add some upload, it maybe reaches 50 kb/s. I compare it to the ADSL line but I don't really know what is about to be considered as "Too much". Of course, video streaming goes up to over 100 kb/s but if it doesn't cause a slowdown, that is OK. I understand that the administrator takes care that not too much of bandwith is used, but he needs to have it in mind, and needs to make a difference between downloading torrents and movies (which he considers not necessary) and downloading some useful things (like drivers, and programs that can be used to improve system and stuff). So that's the reason why I want to hide my computer. When I want to download something, to not be blocked by application he uses to maintain network or by himself. He, nor his applications can't see what I am downloading and can't know if things I download are "useful" or not. And I want to add one more question... Does playing online games uses too much of bandwith? I don't mean playing simple flash games but playing games like MMORPG or FPS. Well, I am a gamer so I wanna know. Thanks.
