Don't know about servers lists, but I know there is the Steamcloud. Which copies over your settings for each game wherever you log in. It's really nice if you play at lans or friends etc a lot. I know it does game settings and keybinds. Perhaps it might also do servers if you configure it right?
Most likely depends on the game tho. I know a lot of things are stored client side as opposed to server side just because they are chincy.
and btw. The one thing good I will say about MW2. At least they finally started storing your name and achievements server side instead of client side. That way you can't lose it. Although I did think that would almost make it less hack likely. But there are already so many hacks out to get to lvl 70 prestige 10 with everything unlocked. Kind of lame.
