I've wanted something like this forever. Valve's new system, Steam Cloud, will provide an online backup of your configs and savegames that is tied to your account.

It will roll out with support for Valve games only, but hopefully it will also extend to other games that are bought via Steam. I keep all of my configs and savegames backed up on an external hard drive, but if I could just have all that stuff automatically upload and update to my account that would be great. After that all I'd want is for the Steam server browser to work with all my games and not just Valve's, then I'd be 100% set.
