Steam News has word that
the Steam cloud will launch later this week along with the demo for
Left 4 Dead,
storing user preferences online. Word is: "In this first release, the information
stored and accessible through the Steam Cloud includes keyboard, mouse, and
gamepad configurations, as well as multiplayer settings such as spraypaint
images." No user intervention is required to make use of the cloud, and word is
it will "just work," and going forward Cloud support will be free-of-charge to
all publishers and developers using Steam, and Cloud support will be added to
Valve's back catalog.
