No No, In MW2 anyone can invite someone else from their list to the private game as long as they are in the game, doesn't have to be the host to do it also if you have someone on your list playing in that game you can just right click their name and click join and get right in. I don't think MW2 needs an internet connection to play on LAN but then again I may be wrong about that and its easy to set a pass in a private server. MW2 on the PC is pretty much a port of the 360 works pretty much the same. I think the overall game play is better in MW2 than COD4 just some perks are pretty wack but those are easy to shut off in the settings so that everyone plays evenly.
