I worked out about adding games, and the overlay the other week. What about games like CoD4? I mean, that uses both Steam, and it's own thing. If you buy the non-steam version, and you add it to your Steam collection, does it download an update to allow for Steam functionality (game invites, etc.)?

No, but COD4 is messed up in that regard anyway.  I own the Steam version, and when someone joins a game, it doesn't give the option to join...you'll have to send the person the IP of the server...it's the fault of the COD4 guys though, not Steam.

But yeah, if you are playing a non-Steam game, unless it has a code to get Steam functionality?(I believe some games, perhaps just Valve games, have that), you'll have full chat capability using the overlay, but nothing saying what server you're on and whatnot.
