How do I get my lag switch to work for PC games online without my own server?

[????Anonymous????]

I used my lag switch for COD4 on my ps3 and had researched it and found that you have to be the host of the game to use it because it makes everyone else lag, but I don't know how to use it on a PC game (BF2 is the game I want to use the switch for) because certain people are designated as admins and such, so i am confused.
