It'd probably be a part of Steamworks, you're right.
The problem is not finding out WHICH files to upload to the SteamCloud server, but where to put them on the other side. There exist the problem that the game's directory is in a different place, or the game is a different version, or it has already existing saves that would be over-written (e.g. Unreal Tournament's tournament progress data).
